Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

This algebra 2 and precalculus video tutorial explains how to determine whether a function f is even, odd, or neither algebraically and using graphs. This video contains plenty of examples and practice problems using variables and constants. First, plug in -x into the equation and see if the sign changes. If all signs change, it's an odd function. If they all remain the same, then it's an even function. If some change while others do not, the function is neither even or odd. For graphs, even functions are symmetric about the y axis. For odd functions, the symmetry exists about the origin. For circles with even and odd properties, it does not pass the vertical line test and is therefore not a function.

OFFSET tells Excel to “fetch” a cell location (address) from within a data range. Download the Workbook here: http://www.xelplus.com/excel-offset-function-for-dynamic-calculations/
Get the full course: https://courses.xelplus.com/
Excel OFFSET Function Tutorial Summary:
The offset formula looks like:
=OFFSET(starting point, rows to move, columns to move, height, width)
Here are practical uses of OFFSET:
• Dynamic Calculations: The OFFSET formula can be included in other Excel functions to get dynamic ranges. For example, calculating the average sales of the last 3 months based on a selection
• Flexible Chart Ranges: In conjunction with charts it can be used in the NAME manager to add flexibility to chart data. The OFFSET function behaves like an Excel table where the data range automatically expands and contracts when chart data is updated.
• Dynamic dashboards: It can be used together with Excel’s Form Options to allow for dynamic analysis and reports based on user-selection.
You can tell the OFFSET function to return one cell if you specify height and width as 1. It can return an array of cells when the height and width are greater than 1. Height and/or width CANNOT be zero, because you either need 1 cell or a range of cells. In the illustration above, the height and width are 2.
This video shows how you can use the Excel OFFSET function to calculate the average value for the last 6 months. You will also learn how to use the OFFSET formula to calculate the average value based on the date selected by the user.
(You will see formula combinations such as OFFSET, COUNTA and MATCH functions)
In general Excel OFFSET function is an interesting formula and it’s one that can do so much more than meets the eye. It can used inside many formulas to provide them with flexible ranges instead of fixed ranges. This makes it a perfect candidate for dynamic reports and dashboards.

This calculus video tutorial explains how to identify points of discontinuity or to prove a function is continuous / discontinuous at a point by using the 3 step continuity test. This involves evaluating piecewise functions using one sided limits. The first step is to determine if the function is defined at the given point. The second step is to prove that the limit exists by showing that the right side equals the left side. If the limit does not exist, it could be a jump discontinuity or an infinite discontinuity which are nonremovable. The 3rd step is to show that the limit equals the function at the given point. If the limit exists but does not equal the function, then it's a point discontinuity also known as a hole which is removable.

Learn how to compose two functions where one or both of those functions is/are radical. To compose two functions means to express one of the functions as a function of the other function. This is done by replacing the input variable of one of the functions with the value of the second function. We will then simplify the composition and determine the domain.

Quickly master how to find characteristics of quadratic functions. Watch more lessons like this and try our practice at https://www.studypug.com/algebra-help/quadratic-functions/characteristics-of-quadratic-functions
Three properties that are universal to all quadratic functions: 1) The graph of a quadratic function is always a parabola that either opens upward or downward (end behavior); 2) The domain of a quadratic function is all real numbers; and 3) The vertex is the lowest point when the parabola opens upwards; while the vertex is the highest point when the parabola opens downward.
Let's learn some vocabulary for quadratic functions. First, vertex. What is a vertex of a quadratic function? Well, the word vertex means peak. So the vertex of a quadratic function is the peak point on a parabola. Which means for a parabola opening down, the vertex is the highest point. Now for a parabola opening up, the vertex is the lowest point. So in this case, we have a parabola opening up, so the vertex is the lowest point, right here. Sitting at x equals 1, y equals negative 9. So the vertex is at 1 and negative 9. Next, axis of symmetry. The axis of symmetry of a quadratic function, is a vertical line that divides the parabola into two equal halves, like this. And the axis of symmetry must always pass through the vertex. The symmetry behavior can be best understood when we fold the parabola in half along the axis of symmetry. Then the right half of the parabola will completely overlap the left half of the parabola. Can you see that? Let me show you. Here we have a parabola, just like this one, and the axis of symmetry runs down the middle of a the parabola. Now, I'm going to fold the graph along the axis of symmetry. Can you see that? The two halves of the parabola completely overlap each other. Yeah? Cool. Now let's determine the equation of the axis of symmetry. For a vertical line that passes through x equals 1, the equation of the line is simply x equals 1. Because for every point on this vertical line, the x coordinate is always 1. So in this case, the equation of the axis of symmetry is x equals 1. Next, y intercept. The y intercept is the point where the parabola intersects the y axis. So in this case, that's right here and the y intercept is negative 8. Next, x intercepts. The x intercepts are the points where the parabola intersects the x axis. So in this case, the parabola intersects the x axis at two points. One at x equals negative 2 another one at x equals 4. Next, domain. By definition, domain is the set of x values for which a function is defined. So as we can see, a parabola is defined for all x values. Let me show you. This point, the x value is positive 1. This point x value is positive 2. This point x value is positive 3. This point x value is positive 4, and this point x value is positive 5. So a parabola is defined for all positive integers for x. Now if you take any points in between, now see, these points the x values are positive decimal numbers, right? Yeah. So a parabola can take on any positive values for x, whether they are integers or whether they are decimal numbers. Parabola can take on any positive numbers for x. Now, guess what? Parabola can also take on any negative values for x. For example, this point x value is negative 1. This point x value is negative 2. This point x value is negative 3. You see, negative integers. Now, for any point in between them, for any points between the negative integers, this point the x values are all negative decimal numbers. So in conclusion, parabola can take on any positive values for x. Parabola can also take on any negative values for x and parabola can even take on zero for x. That would be this point, for the y intercept, the x value is zero, right? So therefore, the domain for a quadratic function is all real numbers. And we write a mathematical notation like this, x is all real numbers.

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!
