in the graph below, we are testing to see if the vertical line test passes at x= -1. when we draw a vertical line at x=-1, it appears as if the vertical line intersects the graph at two points (-1,2) and (-1,-1). But the vertical line actually only intersects the graph at one of these points. 1. at which point, (-1,2) or (-1,-1), does the vertical line intersect the graph? explain why the vertical line does not intersect the other one of those two points
