WebIf a function does not give all of the input-output pairs for both functions, then it is possible that the functions may not be inverses of each other. In order for two functions to be inverses of each other, they must satisfy the following criteria: 1. Each input of one function corresponds to a unique output of the other function. 2. WebTo find the inverse of a function, you can use the following steps: 1. In the original equation, replace f (x) with y: to. 2. Replace every x in the original equation with a y and every y in the original equation with an x. Note: It is much easier to find the inverse of functions that have only one x term.
