Question Analysis
This question tests the student's understanding of the Vertical Line Test. The key concept is that if every vertical line intersects the graph at most once, the graph represents a function.

Key Concept Explanation
The Vertical Line Test is a graphical method used to determine whether a given graph represents a function. A function must have each input (x-value) corresponding to exactly one output (y-value). If every vertical line intersects the graph at most once, it means there are no x-values that map to more than one y-value, which satisfies the definition of a function.
