Amath problem asks when two brothers will have saved the same amount of money. when marta writes and solves the equation, her final step is 3 = 7. assuming marta has done everything correctly, how should she interpret this solution? a. the brothers started with the same amount of money. b. the brothers will never have the same amount of money. c. the brothers will have the same amount of money in 3 years. d. the brothers will have the same amount of money in 7 – 3 = 4 years.

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.
