Which of the following sets of ordered pairs represent a function? Check all that are true. {(-3, 7), (-2, 7), (-1, 7), (0, 7), (1, 7)} {(1.5, 3), (2.5, 3), (5, -3), (6, 2.5), (9, 11)} {(-27, 15), (14, 2), (37, 0), (14, 15), (-3, 7)} {(15, -2), (-2, 15), (11, 7), (-4, -4), (10.2, 3)} {(1, 2), (3, 4), (5, 6), (6, 10), (7, 40)}

Which of the following represents a number squared is equal to twenty more than nine times that number ? a) x squared = 9x + 20 b) x squared = 20x + 9 c) x squared > 9 + 20x d) x squared = 9 + x + 20

Anyone know? is appreciated! will mark brainliest if correct!

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.
