Inverse function

function which is reached by expressing the dependent variable of one function as the independent variable of another (Mathematics)

In mathematics, if ƒ is a  function from A to B then an inverse function for ƒ, denoted by ƒ−1, is a function in the opposite direction, from B to A, with the property that a round trip (a composition) returns each element to itself. Not every function has an inverse; those that do are called invertible.
