Consider the function .  

  1. Sketch a graph of the function. Label any holes or asymptotes.

    No holes. Two asymptotes: and . Label them.

  2. Write an equation for the inverse of . Is the inverse a function? Why or why not?

  3. Sketch a graph of the inverse and compare this sketch to the graph of  from part (a).

    You do not need to know the inverse equation to sketch a graph of the inverse. Start by switching the horizontal and vertical asymptotes. Then plot some key points, and connect.

Use the eTool below to explore the graphs.
