WebJun 19, 2015 · The inverse function f − 1 is the function which "undoes" the work of f: Formally f ( f − 1 ( y)) = y and f − 1 ( f ( x)) = x for all y in the domain of f − 1 and all x in the domain of f. If f − 1 exists, then the domain and range of f − 1 are precisely the range and domain of f, respectively.
