**Title: Understanding Function Behavior**

**Determine the intervals on which the function is increasing, decreasing, and constant.**

**Graph Description:**

In the given graph, we observe a function plotted over the x-y coordinate plane. The x-axis ranges from -5 to 5 and the y-axis ranges from -5 to 5. The function consists of several distinct segments:

1. **Constant Segment:**
   - From x = -5 to x = -3, the function is constant at y = 2.

2. **Increasing Segment:**
   - From x = -2 to x = 0, the function increases from y = -3 to y = 3.

3. **Decreasing Segment:**
   - From x = 1 to x = 3, the function decreases from y = 3 to y = 1.

4. **Increasing Segment:**
   - From x = 3 to x = 5, the function increases from y = 0 to y = 3.

**Options for Behavior Analysis:**

- A) Increasing on (-2, 0) and (3, 4); Decreasing on (-5, -2) and (1, 3)
- B) Increasing on (1, 3); Decreasing on (-2, 0) and (3, 5); Constant on (2, 5)
- C) Increasing on (-2, 0) and (3, 5); Decreasing on (1, 3); Constant on (-5, -3)
- D) Increasing on (-1, 0) and (3, 5); Decreasing on (0, 3); Constant on (-5, -3)

**Correct Analysis:**

- The function is constant on (-5, -3).
- It is increasing on (-2, 0) and (3, 5).
- It is decreasing on (1, 3).

Thus, the correct option that fits the graph's behavior is:

**C) Increasing on (-2, 0) and (3, 5); Decreasing on (1, 3); Constant on (-5, -3).**
