Question
**Problem Statement:**

The relative maximum value of \( f(x) = x^2 \cdot \sqrt[3]{x - 7} \) is __________, and its relative minimum value is __________.

**Explanation:**
In this problem, we are given a function \( f(x) = x^2 \cdot \sqrt[3]{x - 7} \) and asked to find its relative maximum and minimum values. 

To solve this, we can follow these steps:

1. **Find the first derivative:** Compute \( f'(x) \) to determine where the slope is zero or undefined. These points are potential candidates for relative maxima and minima.
   
2. **Find critical points:** Solve \( f'(x) = 0 \) for \( x \). These solutions are the critical points.

3. **Second derivative test:** Compute \( f''(x) \). Use the second derivative test to identify if each critical point is a relative maximum or minimum.
   
4. **Evaluate the function at critical points:** Substitute the critical points back into \( f(x) \) to find the values of the relative maximum and minimum.

By following these steps, you can determine the relative extrema of the function.

(Note: In a classroom or educational setting, you can include intermediate steps for calculations to aid students' understanding.)
