Inverses of Simple Quadratic and Cubic Functions

The inverse has been reflected over which line?

• y = x

• y =1

• y = 0

• y = x + 1

What's the best description?

• They are both functions, but not 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.

• They are inverse functions.
