My examples have just a few values but functions usually work on.
Vertical line test math.
In order to be a function each x value can only be paired with exactly one y value.
On a graph the idea of single valued means that no vertical line ever crosses more than one value.

The vertical line test supports the definition of a function.
But not all graphs represent functions.

If it crosses more than once it is still a valid curve but is not a function.
Horizontal line test one to one function.

If you think about it the vertical line test is simply a restatement of the definition of a function.

In mathematics the vertical line test is a visual way to determine if a curve is a graph of a function or not.
Is a way to determine if a relation is a function.
States that if a vertical line intersects the graph of the relation more than once then the relation is a not a function.
If you can not then the graph represents 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.
Some types of functions have stricter rules to find out more you can read injective surjective and bijective.
What does vertical line test mean.
That is every x value of a function must be paired to a single y value.

The graphs of functions can be straight lines or segments curves or even just a set of points.
If the graph of a function can only have one output for each unique input then relation is function otherwise not.
Meaning of vertical line test.
The vertical line test.
A test use to determine if a relation is a function.
Vertical line test strategy try to draw a vertical line on the graph so it intersects the graph in more than one place.
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 a method used to check whether or not a relation is a function.
A relation is a function if there are no vertical lines that intersect the graph at more than one point.
