Determine x-values where f'(x) > 0, f'(x) < 0. (Enter your answers using interval notation.) f'(x) > 0 f'(x) < 0 (d) Determine x-values for which f(x) has a maximum or minimum point. (Enter your answers as a comma-separated list.) maximum point X = minimum point X = Determine where the graph of f(x) is increasing, and where it is decreasing. (Enter your answers using interval notation.) increasing decreasing
