The horizontal line shown in Figure 17 intersects the graph of the function at two points (and we can even find horizontal lines that intersect it at three points.). The horizontal number line goes from -25 to 25 and stretches 12 feet long, and the vertical number line goes from -20 to 20 and is 6 ft tall. The graph does not pass the vertical line test; therefore, the graph is not a function, and it is a relation only. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because a function has only one output value for each input value.
