A model rocket is launched from the roof of the school building. Its flight path is modeled by h (u) = -5x^2 +15x +32 where h is the height of the rocket above the ground in feet and x is the time after the launch in minutes. How long was the rocket in the air before crashing into the ground? Round to the
nearest tenth

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.
