3. Determine whether the function f (a) = 7-202 satisfy the conditions for the Mean Value Theorem on the interval [-1, 2]. If so, find the point (s) guaranteed t exist by the theorem. (Hint: find a point in -1, 2] at which the tangent line to the curve has a slope equal to the average rate of chance). 4. Sketch the graph of f(x) = 3x3 - 10x2 + 7x + 5. Show working for critical points, intercepts, extremum points, concavity, asymptotes and inflection points
