The graph shown appears to represent a parabola, which opens downward. To determine if this graph represents a function, we can apply the **Vertical Line Test**.

### Vertical Line Test:
- A graph represents a function if, and only if, no vertical line intersects the graph at more than one point. 
- In this graph, no vertical line would intersect the curve at more than one point.

Since this parabola passes the vertical line test, the graph **is a function**.

Here are five related questions for further exploration:
1. What is the equation of this parabola?
2. How can you find the vertex of a parabola?
3. What is the domain and range of this function?
4. How does the orientation of the parabola (upward vs downward) affect its properties?
5. Can every parabola be expressed as a quadratic function?

**Tip:** When determining if a graph is a function, always remember to use the vertical line test!
