Consider the following function. foo = (x - 6)\"3 Find the derivative of the function. f'(X) = 3(X _ 6) / Great work! (15) Find all the values ofx for which f'(x) = 0 or f'(x) is discontinuous. (Enter your answers as a comma-separated list.) x: Find the interval(s) where the function is increasing and the interval(s) where it is decreasing. (Enter your answers using interval notation. If the answer cannot be expressed as an interval, enter EMPTY or 0.) increasing decreasing
