Use the Horizontal Line Test to determine whether the inverse of f is a function.

• function

• not a function

Use the Horizontal Line Test to determine whether the inverse of f is a function.

• function

• not a function

What is the best description?

• They are both functions, but not inverse functions.

• They are inverse functions.

• They are reflected over y=x, but they are not both functions.

• They are not reflected over y=x, and they are not both functions.

 f and g are inverses of each other and drawn on the same graph, with the same scale on both the horizontal and vertical axis. Which of the following would be true?

•  The graph of g is the same as the graph of f, translated up 3 units.

• By rotating the graph of f 90° clockwise around the origin you would get the graph of g.

• By rotating tnhe graph of f  180° clockwise around the origin you would get the graph of g.
