Module 6: Lesson 4
 
Are You Ready?

    1. The graphs of the two functions are shown.

       
      This is a graph of two functions as well as the image line y equals x. One function is at y equals x plus 4; the other function is at y equals x minus 4. The two graphs are inverses of each other.

      Because the two graphs are reflections of each other about the line y = x, the two functions are inverses of each other.
