The following graph fails the vertical line test and is not a function. If we think of a vertical line as an infinite set of x-values, then intersecting the graph of a relation at exactly one point by a vertical line implies that a single x-value is only paired to a unique value of y. Use the vertical line test to determine whether the following graph represents a function. Worksheet (Algebra) Answer Key: No . Answer: A In the above graph, the vertical line intersects the graph in at most one point, then the given graph represents a function. Observe the graph: Consider vertical line at , it touches the graph at . 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. Practice your knowledge of horizontal and vertical lines: their graphical presentation, their slopes, and their equations. 14a. In order to be a function, each x value can only be paired with exactly one y value.
