Purpose of Inverse Functions - Mathematics Stack Exchange

WebThe inverse is usually shown by putting a little "-1" after the function name, like this: f-1(y) We say "f inverse of y" So, the inverse of f (x) = 2x+3 is written: f-1(y) = (y-3)/2 (I also used y instead of x to show that we are using a different value.) Back to Where We Started WebJan 22, 2024 · 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.
