The vertical line test involves drawing a vertical line anywhere on the graph and seeing if it intersects the graph in more than one point. If it does, then the graph does not represent a function. In the given graph, there are multiple points where a vertical line intersects the graph in more than one point, indicating that it is not a function. Therefore, the correct choice is A.
