WebProperties of inverse function are presented with proofs here. Below f is a function from a set A to a set B . Property 1: If f is a bijection, then its inverse f -1 is an injection. Proof of Property 1 : Suppose that f -1(y1) = f -1(y2) for some y1 and y2 in B. Then since f is a surjection, there are elements x1 and x2 in A such that y1 = f ... WebIf f (x) = (x − 1) 3 and g (x) = x 3 + 1, f (x) = (x − 1) 3 and g (x) = x 3 + 1, is g = f − 1? g = f − 1? Finding Domain and Range of Inverse Functions The outputs of the function f f are …
