## Problem 2: Evaluating Statements on Calculus Concepts

For each of the following statements, determine if they are true or false. In either situation, explain your answer.

### a. Maximum Value of a Differentiable Function

For a differentiable function \( f \) on the interval \([-2,1]\), its maximum value must occur at either \( x = -2 \) or \( x = 1 \).

\[ \boxed{\ } \]

*(This implies analyzing the behavior of the function within a closed interval, considering the endpoints and any critical points in the interior.)*

### b. Classification of Critical Points

The first derivative test can classify critical points that the second derivative test cannot.

\[ \boxed{\ } \]

*(Discuss the scenarios where the first derivative test is useful, especially when the second derivative test is inconclusive, such as inflection points or points where the second derivative is zero.)*

### c. Applying Rolle's Theorem

On the interval \([-4,4]\), the function \( f(x) = 2 + x^{2/3} \) satisfies the conditions of Rolle’s theorem.

\[ \boxed{\ } \]

*(Examine the continuity and differentiability of the function on the given interval, and verify if the endpoints satisfy Rolle's theorem conditions. Consider the nature of the function’s derivative.)*
