A function can only have one output y for each unique input x if a vertical line intersects a curve on an xy plane more than once then for one value of x the curve has more than one value of y and so the curve does not represent a function.
Vertical line test meaning in math.
Vertical line test a method used to check whether or not a relation is 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.

The vertical line test supports the definition of a function.
A relation is a function if there are no vertical lines that intersect the graph at more than one point.
On a graph the idea of single valued means that no vertical line ever crosses more than one value.
That is every x value of a function must be paired to a single y value.
Vertical line test is generally done by using a ruler.
In mathematics the vertical line test is a test to determine if a curve is a relation or graph of a function when the function s domain and range correspond to the x and y axis of the cartesian coordinate.
