In mathematics, a function that can reverse another function is known as an inverse function, or anti-function. Consider a function "f" that converts x to y. The inverse of the function "f" is one that converts y back to x, denoted as f(x) = y ? f?¹(y) = x. An inverse function calculator is often used by students to quickly find the inverse of a given function.
Finding the Inverse of a Function Without an Inverse Function Calculator An inverse function is one that undoes the action of another function. While an inverse function calculator is a helpful tool, it’s possible to determine an inverse function manually by following these steps:
If you're trying to find the inverse of a function without using a calculator, you can start by switching the function's variables and then solve for the other variable.
Find the inverse of the function:
f(x) = y = 4x - 1
Solution:
Start by replacing f(x) with y:
y = 4x - 1
Now, switch x and y:
x = 4y - 1
Solve for y:
y = (x + 1) / 4
So, the inverse function is:
f-1(x) = (x + 1) / 4
Find the inverse of the function:
y = (x + 7) / (3x + 5)
Solution:
First, swap x and y:
x = (y + 7) / (3y + 5)
Multiply both sides by (3y + 5):
x(3y + 5) = y + 7
Expand and rearrange:
3xy + 5x - y = 7
y(3x - 1) = 7 - 5x
Solve for y:
y = (7 - 5x) / (3x - 1)
Thus, the inverse function is:
f-1(x) = (7 - 5x) / (3x - 1)

No need to stress about finding a function's inverse manually—use our calculator for fast and accurate results. Try it for free and see how it can simplify your calculations.
In mathematics, the terms "reciprocal" and "inverse" are related but have different meanings. The reciprocal of a number 'a' is 1/a, and it is the number that, when multiplied by 'a,' results in 1. For a fraction x/y, the reciprocal is y/x. The reciprocal is useful in simplifying arithmetic operations and can often be computed mentally.
Despite their similarities, reciprocal and inverse functions are not the same. The inverse function reverses another function, whereas the reciprocal involves flipping a number or fraction.

An inverse function in mathematics is a function that reverses the effect of another function. If a function ? ( ? ) = ? f(x)=y is given, the inverse function would be ? ? 1 ( ? ) = ? f ?1 (y)=x.
To use the inverse function calculator, enter the function you want to inverse into the provided field, click the "Inverse" button, and the calculator will display the inverse function.
The concept of the inverse function was introduced by John Frederick William Herschel.
An inverse function calculator simplifies the process of finding the inverse of a function, saving time and reducing the risk of errors, especially with complex functions.
