  1. Use the equation f(x) = (x + 3)3 − 1 to complete each of the following tasks. Homework Help ✎

    1. Find the inverse equation.

    2. Graph the inverse equation.

    3. Is the inverse a function? Explain.

y = (x + 3)3 − 1 Switch x and y.
x = (y + 3)3 − 1
(x + 1) = (y + 3)3

Reverse the x- and y-coordinates.

Is there only one output (y) for each input (x)?
