Question Analysis
This question tests the basic understanding of the Vertical Line Test and its application to determine whether a given graph represents a function.

Key Concept Explanation
The Vertical Line Test is used to check if each input (x-value) corresponds to exactly one output (y-value). If a vertical line intersects the graph at more than one point, it means that there is at least one x-value that maps to more than one y-value, which violates the definition of a function.
