Answer

$f(x)$ satisfies the hypotheses (see below for reasons)

Work Step by Step

The two hypotheses of the Mean Value Theorem are: (1) $y=f(x)$ is continuous over a closed interval $[a, b]$ and (2) $y$ is differentiable on the interval's interior $(a, b)$ . --- In this problem, (1) $f(x)$ is continuous over $[0,1]$ due to Th.8. (properties of continuous functions, sec. 2.5) (2) $f(x)$ is differentiable on $(0,1)$ due to the Power Rule (general version, sec.3.3) Thus, $f(x)$ satisfies the hypotheses.
