Chase is trying to calculate the total cost of the T-shirt that he's buying. Since it's on sale, he first found the amount of the discount and added that to the original price. Next, he subtracted off the amount of the sales tax. His total, though, is different than the sales clerk's total. What did Chase do wrong? a. He should have subtracted the discount.
b. He should have added the sales tax.
c. He should have subtracted the discount and added the sales tax.
d. Nothing. The sales clerk has the wrong total.

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.
