Determine whether Rolle's Theorem can be applied to f on the closed interval [a, b]. (Select all that apply.)

f(x) = 6 cos x, [0, 2]

Yes, Rolle's Theorem can be applied.No, because f is not continuous on the closed interval [a, b].No, because f is not differentiable in the open interval (a, b).No, because f(a) f(b). If Rolle's theorem can be applied, find all values of c in the open interval (a, b) such that

f'(c) = 0.

(Enter your answers as a comma-separated list. If Rolle's Theorem cannot be applied, enter NA.)

c =
