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. Created by Sal Khan.

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

Review your knowledge of the inverse trigonometric functions, arcsin (x), arccos (x), & arctan (x).

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 …

Learn how to build a mapping diagram for a finite function, and how to use this diagram to determine if the function is invertible. An invertible function has a one-to-one mapping between its domain and …

Learn about inverse functions in algebra, including their properties and how to find them.

Learn about inverse functions with Khan Academy's comprehensive video tutorials and exercises.

What are inverse functions? Inverse functions are functions that "undo" each other. If we plug the output of one function into the inverse function, we get back the original input. Practice with our Evaluate …
