### Calculus Exercise on Finding Absolute Extrema

**Problem Statement:**

Find the absolute maximum and minimum values of \( f(x) = 2x^3 - 3x^2 - 12x \) for \( 0 \leq x \leq 3 \).

**Instructions:**

To solve this problem, you will need to:

1. **Find the critical points** of the function \( f(x) \) by taking the derivative and setting it to zero.
2. **Evaluate the function** at the critical points as well as at the endpoints of the interval.
3. **Compare the values** to determine the absolute maximum and minimum.

**Detailed Explanation:**

1. **Derivative Calculation:**
\[ f'(x) = \frac{d}{dx} (2x^3 - 3x^2 - 12x) \]

2. **Setting the derivative to zero** to find critical points:
\[ 0 = 6x^2 - 6x - 12 \]

3. **Solve for \( x \):**
\[ x = \text{values obtained from solving the quadratic equation} \]

4. **Evaluate \( f(x) \) at the critical points** and at \( x = 0 \) and \( x = 3 \).

5. **Compare the values** to find the absolute maximum and minimum.
