I need my explanation checked for this please.
If a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.It does not pass the “vertical line test”, which requires all vertical lines to intersect the graph at one point. Since a vertical line touches the relation at two points (1, 1) and (1, 3) at x = 1 this is not a function.
