What is an Inverse Function?
In mathematics, an inverse function (or anti-function) is a function that "reverses" another function. If a function f takes an input x and produces an output y, then the inverse function f⁻¹ takes the output y and produces the input x. In simpler terms, if f(x) = y, then f⁻¹(y) = x.
For example, if f(x) = x + 2, then the inverse function is found by solving y = x + 2 for x in terms of y, which gives x = y - 2. So, f⁻¹(x) = x - 2. This tool helps you find the inverse of simple functions and visualize them graphically.
