In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective , and if it exists, is denoted by f − 1 . {\displaystyle f^{-1}.}
Learn what inverse functions are, how to find them and how to graph them. See the rules, formulas and examples for common functions and their inverses, and how to restrict the domain for bijective functions.
17 sie 2024 · An inverse function reverses the operation done by a particular function. In other words, whatever a function does, the inverse function undoes it. In this section, we define an inverse function formally and state the necessary conditions for an inverse function to exist.
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.

What Is an Inverse Function? The inverse function f − 1 undoes the action performed by the function f. We read f − 1 as “f inverse.” If f − 1 is an inverse of the function f, then f is an inverse function of f − 1. Thus, we can say that f and f − 1 reverse each other.
