Question Analysis
This question tests the student's ability to apply the Vertical Line Test to a specific vertical line. The key concept is that if a 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 a 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.
Step-by-step Solution
1. Identify the graph to be tested.
2. Draw a vertical line at
