8.) Verizon charges a one time sign up fee of $95 and then $49.99 per month for an unlimited phone service. AT&T charges a one time sign up fee of $70 and then $59.99 per month for the
same phone service. Pick the correct equation below that models when the two phone
companies will charge the same price.

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.
