Inverse radical functions

This use of “–1” is reserved to denote inverse functions. To denote the reciprocal of a function f(x), we would need to write: (f(x)) − 1 = 1 f(x). An important relationship between inverse functions is that they “undo” each other. If f − 1 is the inverse of a function f, then f is the inverse of the function f − 1.
