Function Inverses Example 1

Curated and Reviewed by Lesson Planet

Sal continues looking at function inverses in this video by showing two examples. In each example, he finds the inverse and shows the graph of both functions. Both of his examples are with linear functions, but his first example shows a function whose inverse is the same as the function. You might consider having students find the inverse of such a function and see if they can determine why its inverse is the same and why it make sense, before you have them watch this video.
