-=== What It's For ===
+#REDIRECT[[Vertical line test]]
-The '''vertical line test''' is a way of determining if a plotted [[graph]] is a [[function]].

-If a vertical line can be placed anywhere on the graph such that it touches two points, then the graph is not a [[function]]. This is because a [[function]] cannot have more than one output for one input.
