"WebFormally speaking, there are two conditions that must be satisfied in order for a function to have an inverse. 1) A function must be injective (one-to-one). This means that for all values x and y in the domain of f, f (x) = f (y) only when x = y. So, distinct inputs will produce distinct outputs. 2) A function must be surjective (onto).

WebTo find the inverse of a function, you need to do the opposite of what the original function does to x. Example Not all functions have inverses. A function must be a one-to-one function, meaning that each y -value has a unique x -value paired to it. Basically, the same y -value cannot be used twice. WebApr 17, 2024 · Intro to Finding the Inverse of a Function Before you work on a find the inverse of a function examples, let’s quickly review some important information: Notation: The following notation is used to denote a function (left) and it’s inverse (right).
