HELP Which situation can be represented by the equation y=12x?
A.) Victoria went to school for x years. This is 12 times y, the number of years her brother went to school.
B.) Victoria spent x dollars to buy a gift for her brother. She gave the cashier y dollars and received $12 in change.
C.) Victoria has y dollars. This amount is 12 times x, the amount of money in dollars Victoria's brother has.
D.) Victoria is y years old. Her age is 12 years greater than x, her brother's age in 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.
