To determine if the given relation is a function, we can use the Vertical Line Test. A relation is considered a function if every vertical line drawn through the graph intersects the graph at most once.

In this case, the graph shown represents a curve, and it does pass the vertical line test. For any vertical line drawn, it will only intersect the curve at one point. Therefore, this relation is a function.

Tip: Always apply the vertical line test when you're unsure whether a graph represents a function!
