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.

WebThe composition of two inverse functions always equals to x. This is how inverse functions can be verified algebraically. I'll omit the algebraic check here, since f⁻¹(x) is already not a function.
