The ceiling of Xavier’s living room is a square that is 12 ft long on each side. To decorate for a party, he plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner.
Xavier can buy rolls that each contain 10 ft of crepe paper. What is the minimum number of rolls he should
buy? Show all your work

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
