Explain why Rolle's theorem does not apply to the function even though there exist a and b such that f(a) = f(b). (Select all that apply.) f(x) = cotl [π, 3π] There are points on the interval (a, b) where f is not differentiable. There are points on the interval [a, b] where f is not continuous. O f(a) does not equal f(b) for all possible values of a and b in the interval [π, 3π]. O f'(a) does not equal f'(b) for any values in the interval [7, 3π]. None of these. 000
