a. Find the inverse of ƒ(x) = x + 1. 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 ƒ(x) = x + b (b constant). How is the graph of ƒ ^-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?
