Inverse Functions

One-One Functions – Part 1– This screencasts demonstrates what we mean by one-to-one functions
One-One Functions – Part 2 – This screencast gives some examples of determining if a function is one-one and describes how to restrict a function to make it one-to-one.
Introduction to Inverse Functions– This screencast demonstrates the meaning of an inverse function including the use of inverse notation.
Determining if a function has an inverse– This screencast demonstrates how to determine if a function has an inverse and shows how to restrict the domain of a function.
Finding the inverse of a function symbolically – Part 1a – This screencast demonstrates how to find the inverse of a function symbolically. Viewers are asked to do an example alongside the demonstration example.
Finding the Inverse Function Graphically – This screencast demonstrates how to find the inverse of a function graphically.
Finding the inverse of a function symbolically – Part 1b– This screencast demonstrates how to find the inverse of a function symbolically. Viewers are asked to do an example alongside the demonstration example.
Verifying that two functions are inverses of each other – This screencast demonstrates how to verify that two functions are inverses of each other. At the same time students are asked to complete their own example
