To solve the given problem based on the graph provided, we need to analyze the behavior of the function \( f(x) \) and its derivative \( f'(x) \) at specific points. I'll walk through each part:

### For \( f(x) \):
1. **(a) \( f(-2) \)**: 
   - At \( x = -2 \), the graph shows the function value \( f(x) \) is slightly below 0.
   - Answer: **Negative**.

2. **(b) \( f(0) \)**: 
   - At \( x = 0 \), the graph crosses the x-axis at \( f(0) = 0 \).
   - Answer: **Zero**.

3. **(c) \( f(4) \)**: 
   - At \( x = 4 \), the function value \( f(4) \) is positive, as it is above the x-axis.
   - Answer: **Positive**.

4. **(d) \( f(5) \)**: 
   - At \( x = 5 \), the graph shows \( f(5) \) is negative, below the x-axis.
   - Answer: **Negative**.

### For \( f'(x) \) (Slope of the graph):
5. **(e) \( f'(-2) \)**: 
   - At \( x = -2 \), the slope is positive as the function is increasing.
   - Answer: **Positive**.

6. **(f) \( f'(2) \)**: 
   - At \( x = 2 \), the slope is zero as it is the turning point (maximum point on the graph).
   - Answer: **Zero**.

7. **(g) \( f'(4) \)**: 
   - At \( x = 4 \), the slope is negative as the function is decreasing.
   - Answer: **Negative**.

8. **(h) \( f'(5) \)**: 
   - At \( x = 5 \), the slope is positive as the function starts increasing again.
   - Answer: **Positive**.

Would you like further details on any specific part? Here are five related questions:

1. How do you determine the sign of the derivative using a graph?
2. Why does the derivative equal zero at a turning point?
3. Can a function's value be negative while its slope is positive? How?
4. What happens to the slope of a function as you move past a local minimum or maximum?
5. How would you interpret the second derivative based on a graph?

**Tip:** Remember, when analyzing \( f'(x) \), you're checking the slope of the tangent line at each point!

Use the graph shown to decide if each quantity appears to be positive, negative, or zero: f(-2), f(0), f(4), f(5), f'(-2), f'(2), f'(4), f'(5)

Analyze a graph to determine whether the function and its derivative are positive, negative, or zero at specific points. Explore core concepts of functions and derivatives, ideal for high school math students.
