Aball is thrown from an initial height of 7 feet with an initial upward velocity of 23/fts. the ball's height h (in feet) after t seconds is given by the following.
h=7+23t-16t^2
find all values of t for which the ball's height is 15 feet.
round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.)

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.
