An inverse function goes the other way! Let us start with an example: Here we have the function f (x) = 2x+3, written as a flow diagram:

Jul 23, 2025 · An inverse function or also widely known as "anti function" is a function that reverses the result of given another function.Such as if an f (x) = 11, then, its inverse function …

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 …

The inverse function is a function obtained by reversing the given function. The domain and range of the given function are changed as the range and domain of the inverse function. Let us …

A function has an inverse if and only if it is one-to-one (or bijective). A function f has an inverse function if and only if, for every element y in its range, there is only one value of x in its domain …

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 …

Nov 22, 2025 · Learn what an inverse function is, when a function is invertible, and how to find its inverse step by step. Includes definitions, examples, and conditions for bijectivity.

Learn how to find the formula of the inverse function of a given function. For example, find the inverse of f (x)=3x+2. Inverse functions, in the most general sense, are functions that "reverse" …

The commonest inverse functions are, the inverses to powers like x k xk which are called roots and denoted as x 1 k xk1 and the inverse to the exponent function, exp (x) exp(x), which is …

Inverse functions are a way to "undo" a function. In the original function, plugging in x gives back y, but in the inverse function, plugging in y (as the input) gives back x (as the output). If a …
