WebHow Do You Find the Inverse of a Function? The following sequence of steps help in finding the inverse of a function. Here we consider a function f (x) = ax + b. For the given function f (x) = ax + b, replace f (x) = y, to obtain y = ax + b. Interchange the x with y and the y with x in the function y = ax + b to obtain x = ay + b. Web16 de nov. de 2024 · Given the function f (x) f ( x) we want to find the inverse function, f −1(x) f − 1 ( x). First, replace f (x) f ( x) with y y.
