Quadrilateral ABCD is inscribed in circle P as shown. Which statement is necessarily true? A. m∠A + m∠B = m∠C + m∠D B. m∠A + m∠C = m∠B + m∠D C. m∠A + m∠D = m∠B + m∠C D. m∠A + m∠B = 2(m∠C + m∠D)

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.
