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

Key Concept Explanation
A function is a special type of relationship where each input (independent variable) has a unique output (dependent variable). The Vertical Line Test is a method to determine if a graph represents a function: if any vertical line intersects the graph at more than one point, it is not a function.

Step-by-step Solution
1. Understand the Vertical Line Test: A vertical line drawn on the graph should intersect the graph at most one point.
2. Apply the test: Draw several vert...
