• No, they don't reflect.

Which of the following best describes the graph?

• 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.

What's the best description?

• Yes

Which statement about graphs and their inverses is true?

• They are symmetric about the x-axis.

Are these functions inverses of each other?

M = 3N - 12

N = 4 + 1/3M

hint: choose a value for N to find M. See if (M,N) is a part of the other function.

• Inverse Functions

• Not Inverse Functions
