In mathematics, the inverse function is a function that undoes another function. For example, given the function f(x) = 2x. If you input a into the function f, the output is 2a. The inverse function of f(x) is the function g(x) such that if you input 2a into g(x) its output is a. Now what is g(x) equal to? How does its… Read More »
