Answer:
Graph A
Step-by-step explanation:
1. The vertical line test is a visual method to determine if a line on a graph is a function or not. A function can only have one output, y, for each unique input, x.
2. If a vertical line intersects the graph in all places at only one point, that means the relation is a function.
3. If a vertical line intersects the graph in some places at more than one point, then the relation isn't a function.
4. Graph A is the only graph that doesn't pass the vertical line test because if I were to draw a line in some places, it would intersect the graph at more than one point.
Therefore, the correct answer is Graph A.
