**Sketch the Graph of a Function with Given Conditions**

Given Conditions:
1. \( f'(0) = f'(4) = 0 \)

2. \( f'(x) = 1 \) if \( x < -1 \)

3. \( f'(x) > 0 \) if \( 0 < x < 2 \)

4. \( f'(x) < 0 \) if \( -1 < x < 0 \) or \( 2 < x < 4 \) or \( x > 4 \)

5. \( \lim_{{x \to 2^-}} f'(x) = \infty \) 

6. \( \lim_{{x \to 2^+}} f'(x) = -\infty \) 

7. \( f''(x) > 0 \) if \( -1 < x < 2 \) or \( 2 < x < 4 \)

8. \( f''(x) < 0 \) if \( x > 4 \)

**Explanation:**
- \( f'(x) \) describes the slope or rate of change of the function. When \( f'(x) = 0 \), the function has a horizontal tangent, usually at local maxima, minima, or points of inflection.
- \( f'(x) > 0 \) indicates the function is increasing.
- \( f'(x) < 0 \) indicates the function is decreasing.
- \( \lim_{{x \to 2^-}} f'(x) = \infty \) shows the slope approaches positive infinity as \( x \) approaches 2 from the left.
- \( \lim_{{x \to 2^+}} f'(x) = -\infty \) shows the slope approaches negative infinity as \( x \) approaches 2 from the right, suggesting a vertical asymptote.
- \( f''(x) \) is the second derivative, indicating concavity. \( f''(x) > 0 \) implies the function is concave up, and \( f''(x) < 0 \) means it is concave down.
