For a function to have an inverse, the relationship must be that there is a 1-to-1 relationship between its input values and its output values. A quadratic equation doesn't have an inverse because 2 inputs …

Intro to inverse functions Inputs & outputs of inverse functions Graphing the inverse of a linear function Finding inverse functions: linear

The definition of an inverse function is a function that undoes the action of another function (or reverses the action of another function). So yes, it is when the domain and range values are swapped.

Learn how to verify whether two functions are inverses by composing them. For example, are f (x)=5x-7 and g (x)=x/5+7 inverse functions? This article includes a lot of function composition. If you need a …

Learn what the inverse of a function is, and how to evaluate inverses of functions that are given in tables or graphs.

Not all functions have inverses. Those who do are called "invertible." Learn how we can tell whether a function is invertible or not. Inverse functions, in the most general sense, are functions that "reverse" …

We can compose functions by making the output of one function the input of another one. This simple-yet-rich idea opens up a world of fascinating applications. Inverse functions undo each other when …

In the first inverse function video, I talked about how a function and their inverse-- they are the reflection over the line y equals x. So where's the line y equals x here?

Logarithms are the inverses of exponents. They allow us to solve challenging exponential equations, and they are a good excuse to dive deeper into the relationship between a function and its inverse.

A function will map from a domain to a range and you can think of the inverse as mapping back from that point in the range to where you started from. So one way to think about it is, we want to come up with …
