The vertical line test involves tracing a vertical line across the entire graph. If the line intersects the graph at only one point for every value of x, then the graph represents a function. However, if the line intersects the graph at two or more points for any value of x, then the graph does not represent a function. In the given graph, there are multiple vertical lines that intersect the graph at two points, which violates the vertical line test. Therefore, the graph is not a graph of a function, and the correct choice is B. The vertical line test is a method to determine if a graph is a function. If any vertical line intersects the graph in more than one point, then the graph is not a function. In the given graph, there are vertical lines that intersect the graph in more than one point, indicating that it is not a function. Therefore, the answer is B) No.
