What is an inverse function and how do you find it? Essential Vocabulary Inverse Function Domain Range Reflection
3
The inverse of a function is a function if and only if the original function is one-to- one.
The inverse of a function switches all the x and y values. The graph of an inverse function is a reflection over the line y = x Inverse Relations!
4
Examples: Reflect each graph over the line y = x. a) b)
5
Functions f and g are inverses of each other provided:
π π π₯ =π₯ πππ π π π₯ =π₯ Inverse Relations!
