WebThe inverse function would not be a function anymore. If a function is not one-to-one, you will need to apply domain restrictions so that the part of the function you are using is one-to-one. To find the inverse of a function, you can use the following steps: 1. In the original equation, replace f(x) with y: to. 2. WebApr 30, 2015 · A function y = f(x) has an inverse if there exists another function y = g(x) such that for all x f(g(x)) = x and g(f(x)) = x. (It is possible that only one of these formulas hold. In that case we would talk about right and left inverses.) If a function is not injective, then there are two distinct values x1 and x2 such that f(x1) = f(x2).
