We don't need derivatives for this, right?

What are the critical x-values for the function.. 

There are two types of critical values:  the roots of f '(x) = 0, and any values at which the derivative is undefined.  Since the derivative of your function f(x) is never zero, just focus on the critical values of the first kind:  Find the derivative of f(x) using the chain rule, set the result = to 0, and solve for x.
