Question Analysis
This question tests the student's understanding of the Vertical Line Test. The key concept is that if a vertical line intersects the graph at more than one point, the graph does not represent 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 a vertical line intersects the graph at more than one point, it means there is an x-value that maps to more than one y-value, which violates the definition of a function.
