Are the following inverses of each other? Verify the two are inverses.

• True

• False

What is the best description of f(x) in red and g(x) in green?

• They are both functions, but not inverse functions.

• They are inverse functions because they both are functions and they are reflections of each other over y = x.

• 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.

Which of the following pairs of functions are inverses?

• y = 3x + 4 and y = 3x - 4

• y = x + 5 and y = 5 + x

• y = 1/2x + 4 and y = 2x - 8

• y = 1/4x + 12 and y = 4x - 3
