Information and translations of vertical line test in the most comprehensive dictionary definitions resource on the web.
Vertical line test math.
The vertical line test supports the definition of a function.
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.
But not all graphs represent functions.
That is every x value of a function must be paired to a single y value.
States that if a vertical line intersects the graph of the relation more than once then the relation is a not a function.
Some types of functions have stricter rules to find out more you can read injective surjective and bijective.
The graphs of functions can be straight lines or segments curves or even just a set of points.
If it crosses more than once it is still a valid curve but is not a function.
My examples have just a few values but functions usually work on.
Vertical line test strategy try to draw a vertical line on the graph so it intersects the graph in more than one place.
If you can not then the graph represents a function.
Is a way to determine if a relation is 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.
A test use to determine if a relation is a function.
In order to be a function each x value can only be paired with exactly one y value.
A relation is a function if there are no vertical lines that intersect the graph at more than one point.
If the graph of a function can only have one output for each unique input then relation is function otherwise not.
