a student needs to make a rectangular cardboard piece that is 12 inches long. the area of the cardboard piece should be between 60 square inches to 300 square inches. the function f(w) relates the area of the cardboard, in square inches, to the width w in inches. which of the following shows a reasonable domain for f(w)?
a: 2 ≤ w ≤ 5
b: 5 ≤ w ≤ 25
c: 25 ≤ w ≤ 60
d: 60 ≤ w ≤ 300

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.
