3. Verify that f (x) =x satisfies the conditions of the Mean Value Theorem on the closed interval [-1,2]. x+2 Then find all values of c in the open interval (-1, 2) that satisfy the conclusion of the theorem. 4. Use Calculus to graph g(x) = x* +4x. Make sure that your graph shows all intercepts, extrema, and inflection points. Show additional work on the back of the first page, if needed
