inverse function

n. Mathematics
A function whose relation to a given function is such that their composite is the identity function. It is often found by interchanging dependent and independent variables.

in′verse func′tion

Math. the function that replaces another function when the dependent and independent variables of the first function are interchanged for an appropriate set of values of the dependent variable.
