10-131.

Use the equation

*f*(*x*) = (*x*+ 3)^{3}− 1 to complete each of the following tasks. Homework Help ✎Find the inverse equation.

Graph the inverse equation.

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*)?
