Four students measure the length of a minute-long trial four times. they record their measurements as shown.

julian:
57.3 seconds, 58.8 seconds, 59.5 seconds, 62.1 seconds

mia:
58 seconds, 59 seconds, 60 seconds, 61 seconds

sonu:
50 seconds, 60 seconds, 60 seconds, 70 seconds

parul:
57.23 seconds, 59.32 seconds, 62.34 seconds, 63.91 seconds

whose measurements were the most precise?

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.
