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

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

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.

A function will map from a domain to a range and you can think of the inverse as mapping back from that point in the range to where you started from. So one way to think about it is, we want …

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.

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 …

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 …

Practice finding the formula of the inverse function of a given linear function.

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!

Let's find out angle O: angle O is adjacent to line OE, opposite of line ZE, and our hypotenuse is OZ, so you can freely pick between any of the inverse trig functions to answer.
