To find the critical points of a function, we need to find the values of x for which f'(x) = 0 or f'(x) is undefined. From the given derivative, we can see that f'(x) = 0 at x = -2 and x = -9 (because one of the factors must be zero for the product to be zero). Therefore, -2 and -9 are the critical points of f(x).
