How to see if a function is invertible

WebHow do you tell if a function is invertible from a graph? It is based on interchanging letters x & y when y is a function of x, i.e. y = f (x). Then solve for this (new) y, and label it f–1(x). If f (x) passes the HORIZONTAL LINE TEST (because f is either strictly increasing or strictly decreasing), then and only then it has an inverse. WebAn invertible function is one for which we can find an inverse function. Recall that a function maps its input to a unique value. For example x^2 maps 3 to 9. And only to 9. …
