1. **State the problem:** Determine if the given graph represents a function using the vertical line test. 2. **Explain the vertical line test:** A graph represents a function if and only if no vertical line intersects the graph at more than one point. 3. **Analyze the graph:** The graph is a quadratic curve opening upwards passing through points approximately (-3,10), (0,0), and (3,8). 4. **Apply the vertical line test:** Since the curve does not intersect any vertical line more than once, it passes the vertical line test. 5. **Conclusion:** Therefore, the graph represents a function. **Final answer:** Yes, the graph is a function.
