The graphs of functions can be straight lines or segments curves or even just a set of points.
Vertical line test math.
The vertical line test is a visual test that you can use to quickly check and see if a graph represents a function.
In order to be a function each x value can only be paired with exactly one y value.
The vertical line test supports the definition of a function.
Meaning of vertical line test.
That is every x value of a function must be paired to a single y value.
Terms and formulas from algebra i to calculus.
What does vertical line test mean.
States that if a vertical line intersects the graph of the relation more than once then the relation is a not a function.

Vertical line test definition vertical line test is relation between two terms like between x and y term vertical line test is graphical representation to determine if a relation is function or not.
Vertical line test a method used to check whether or not a relation is a function.
The vertical line test.
Some types of functions have stricter rules to find out more you can read injective surjective and bijective.
But not all graphs represent functions.
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.

If the graph of a function can only have one output for each unique input then relation is function otherwise not.
My examples have just a few values but functions usually work on.
If you can not then the graph represents a function.

If it crosses more than once it is still a valid curve but is not 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 relation is a function if there are no vertical lines that intersect the graph at more than one point.
Is a way to determine if a relation is a function.
On a graph the idea of single valued means that no vertical line ever crosses more than one value.
