Learn what the inverse of a function is, and how to evaluate inverses of functions that are given in tables or graphs.

Learn how to find the inverse of a function and how to graph it in this video. The inverse function swaps the x and y values of the original function, and the graph of this inverse function is a …

Sal is given a line segment on the coordinate plane, and he graphs the inverse of the function represented by that segment.

Learn how to find the formula of the inverse function of a given function. For example, find the inverse of f (x)=3x+2.

Now, just out of interest, let's graph the inverse function and see how it might relate to this one right over here. So if you look at it, it actually looks fairly identical.

You'll learn how to find and represent inverse functions, restrict domains to ensure functionality, and use compositions to verify inverses. Unit guides are here!

The definition of an inverse function is a function that undoes another function. Say you have a function f (x) that takes in x and outputs y. f inverse of x would take in y and output x. This …

Sal explains what inverse functions are. Then he explains how to algebraically find the inverse of a function and looks at the graphical relationship between inverse functions.

Since we know all of our side lengths now, we just need to use the inverse functions to calculate our angles. Let's find out angle O: angle O is adjacent to line OE, opposite of line ZE, and our …

If a point (a, b) is on the graph of a function, then (b, a) is on the graph of its inverse. You can check that y=x is the perpendicular bisector of the line between these points, so these points …
