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

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.

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

Practice evaluating the inverse function of a function that is given either as a formula, or as a graph, or as a table of values.

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 …

Intro to inverse functions Inputs & outputs of inverse functions Graphing the inverse of a linear function Finding inverse functions: linear

In the first inverse function video, I talked about how a function and their inverse-- they are the reflection over the line y equals x. So where's the line y equals x here?

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

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!

So, like we've said in the first video, in the introduction to inverses, we're trying to find a mapping. Or, if we were to say that y -- if we were to say that y is equal to x plus 2 squared plus 1.
