F (x) = 5 * x ^ (1 / 3) * (x + 9) ^ (2 / 3) what are the monotone increasing and decreasing intervals of this equation? What are the maximum and minimum values?

F (x) = 5 * x ^ (1 / 3) * (x + 9) ^ (2 / 3) what are the monotone increasing and decreasing intervals of this equation? What are the maximum and minimum values?

Obviously, f (x) has two zeros, 0 and - 9
x> It is obvious that f (x) > 0 and increases monotonically when f (x) > 0
