Let's analyze the problem step by step.

You are provided with a graph of the derivative \( f'(x) \), and the task is to determine what the function \( f(x) \) looks like near specific points based on this derivative.

### Key Points of the Derivative Graph \( f'(x) \):

- The derivative \( f'(x) \) represents the slope of the original function \( f(x) \).
- When \( f'(x) > 0 \), the graph of \( f(x) \) is increasing.
- When \( f'(x) < 0 \), the graph of \( f(x) \) is decreasing.
- Where \( f'(x) = 0 \), \( f(x) \) has a critical point (potential maximum, minimum, or a horizontal inflection point).
  
Now let's interpret the derivative graph at each point and match it with the options provided:

1. **Near \( x = 1 \)**:
   - At \( x = 1 \), \( f'(x) \) is positive and decreasing, which means that \( f(x) \) is increasing, but at a decreasing rate. This resembles a curve like **B**, where the slope starts positive but decreases.

2. **Near \( x = 3 \)**:
   - At \( x = 3 \), \( f'(x) \) is equal to 0, indicating a critical point. Just before and after \( x = 3 \), \( f'(x) \) is negative, which means \( f(x) \) is decreasing before and after the critical point. This suggests a local minimum, like **F**.

3. **Near \( x = 5 \)**:
   - At \( x = 5 \), \( f'(x) \) is 0 again, indicating another critical point. The derivative changes from positive before \( x = 5 \) to negative after, indicating that \( f(x) \) reaches a local maximum here, similar to **D**.

4. **Near \( x = 7 \)**:
   - At \( x = 7 \), \( f'(x) \) is negative but increasing (getting less negative), meaning \( f(x) \) is decreasing but starting to level out, which matches a shape like **G**, a curve that is concave up while decreasing.

### Answers:
- Near \( x = 1 \), the graph of \( f \) looks like **B**.
- Near \( x = 3 \), the graph of \( f \) looks like **F**.
- Near \( x = 5 \), the graph of \( f \) looks like **D**.
- Near \( x = 7 \), the graph of \( f \) looks like **G**.

Would you like further clarification on any of these points? 

Here are some follow-up questions that expand on this information:

1. What is the significance of the points where \( f'(x) = 0 \)?
2. How does the concavity of \( f(x) \) relate to the sign of \( f'(x) \)?
3. Can \( f'(x) \) provide information about inflection points of \( f(x) \)?
4. What does it mean for \( f(x) \) if \( f'(x) \) is constant?
5. How would you sketch \( f(x) \) if given a more complex \( f'(x) \) graph?

**Tip:** Always check the behavior of the derivative just before and after critical points to accurately describe the local behavior of the function.
