3. (a). Determine whether Rolle's Theorem applies to f(x) = 32 coz, on [-2, 2]. (b). If so, find the point(s) guaranteed to exist by Rolle's Theorem. 4. (a). Determine whether the Mean Value Theorem applies to f(x) = sin 1 x on [0, 12]. (b). If so, find the point(s) that are guaranteed to exist by the Mean Value Theorem
