WebInverse Function. For any one-to-one function f ( x) = y, a function f − 1 ( x) is an inverse function of f if f − 1 ( y) = x. This can also be written as f − 1 ( f ( x)) = x for all x in the domain of f. It also follows that f ( f − 1 ( x)) = x for all x in the domain of f … WebAn invertible function is one for which we can find an inverse function.
