Factor the expression below.
x2 - 18x+81
o a. (x - 3)(x - 27)
o b. (x+9)(x+9)
o c. (x+3)(x+ 27)
o d. (x - 9)(x-9)

If you answer 2+2 you will get over 80 points

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.
