The graph in the image shows a function \( f(x) \), and you are tasked with determining the intervals where the function is increasing, decreasing, or constant. Let's analyze the function step by step based on its behavior:

1. **Increasing**: A function is increasing if the graph moves upwards as we go from left to right.
   - In this graph, the function appears to be **increasing** from \( x = -5 \) to \( x = 5 \) continuously.

2. **Decreasing**: A function is decreasing if the graph moves downwards as we go from left to right.
   - There is no segment on the graph where the function moves downward. Hence, the function is never decreasing.

3. **Constant**: A function is constant if the graph is flat (horizontal line) as we move from left to right.
   - There are no flat horizontal sections, so the function is never constant.

### Conclusion:
- **Open interval where the function is increasing**: The function is increasing on the interval \( (-5, 5) \).
- **Open interval where the function is decreasing**: None.
- **Open interval where the function is constant**: None.

If you are to select one of the options in part (a), the function is increasing on the interval \( (-5, 5) \).

1. What is the significance of an open interval in function analysis?
2. How do we define whether a function is strictly increasing?
3. Can a function be both increasing and decreasing in different intervals?
4. How do you represent intervals where the function is constant?
5. How does one determine the concavity of the graph based on its slope?

**Tip**: When analyzing graphs, pay attention to the slope—positive slope indicates an increase, and negative slope indicates a decrease.

Use the graph to determine (a) open intervals on which the function is increasing, (b) open intervals on which the function is decreasing, (c) open intervals on which the function is constant.

Determine the open intervals where the function is increasing, decreasing, or constant based on graph analysis. The function is increasing on (-5, 5) and is neither decreasing nor constant.
