To determine where \( f'(x) > 0 \), we need the following information:

1. The function \( f'(x) \) (the derivative of \( f(x) \)) tells us where the original function \( f(x) \) is increasing or decreasing.
2. When \( f'(x) > 0 \), \( f(x) \) is increasing.
3. The intervals where \( f'(x) > 0 \) correspond to the regions where the derivative is positive.

Without the explicit function \( f(x) \) or its derivative \( f'(x) \), I can guide you through the process:

### Step-by-step process:

1. **Find the derivative** \( f'(x) \) (if not already given).
2. **Set the inequality** \( f'(x) > 0 \).
3. **Solve the inequality** to find the values of \( x \) that make the derivative positive.
4. **Identify the open intervals** based on those values of \( x \).

### Choices:

- **Option A**: If there **are** open intervals where \( f'(x) > 0 \), select this option and input those intervals in interval notation.
- **Option B**: If there are **no** open intervals where \( f'(x) > 0 \), select this option.

To proceed further, I'd need the function \( f(x) \) or its derivative \( f'(x) \). Could you provide that, or do you have any additional information about the function?

Let me know if you need any clarifications or details. Here are 5 relevant questions that can help extend your understanding:

1. How do you compute the derivative of a given function \( f(x) \)?
2. What are the key points (critical points) of a function and how do they help in determining where \( f'(x) > 0 \)?
3. What is the role of the second derivative \( f''(x) \) in analyzing intervals of increasing and decreasing behavior?
4. How do you use a sign chart to determine where a derivative is positive or negative?
5. How can you solve inequalities involving the derivative to find intervals of increasing behavior?

**Tip**: Always check where the derivative equals zero or is undefined—these are critical points that could mark transitions between increasing and decreasing behavior.
