car a and car b were in a race. the driver of car b claimed that his car was twice as fast as car a

do you agree with this claim? why or why not?

a.

yes, because the bar for car b is twice as tall as the bar for car a.

b.

yes, because the speed of car b is twice that of car a.

c.

no, because car b was only 10 mi/hr faster than car a.

d.

no, because the vertical scale exaggerates the differences in speed.

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.
