Find the inverse of the given one to one function f. Give the domain and the range of f and of f^-1, and then graph both f and f^-1 on the same set of axes.

f(x) = ³√x - 1

Easiest is usually switch x and y.

Not strictly correct, yet practical, x=root%283%2Cy%29-1
root%283%2Cy%29=x%2B1
%28root%283%2Cy%29%29%5E3=%28x%2B1%29%5E3
y=%28x%2B1%29%5E3
OR
f%5E-1%28x%29=%28x%2B1%29%5E3
