Sample Answer: The vertical line test determines if
one input has exactly one output on the graph. If any
vertical line passes through more than one point on the
graph, then the relation is not a function.
Which did you include in your response?
Draw vertical lines to intersect on a graph.
The relation is a function if there's only one point of
intersection on a graph.
The relation is not a function if there's more than
one point of intersection on a graph.
