a. Find the inverse of Graph ƒ and its inverse together. Add the line y = x to your sketch, drawing it with dashes or dots for contrast.

b. Find the inverse of (b constant). How is the graph of f–1 related to the graph of ƒ?

c. What can you conclude about the inverses of functions whose graphs are lines parallel to the line y = x.
