Is a way to determine if a relation is a function.
Vertical line test definition math.
But not all graphs represent functions.
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.
The vertical line test is a visual test that you can use to quickly check and see if a graph represents a function.
A test use to determine if a relation is a function.
The vertical line test.
A relation is a function if there are no vertical lines that intersect the graph at more than one point.

The graphs of functions can be straight lines or segments curves or even just a set of points.
In order to be a function each x value can only be paired with exactly one y value.
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.
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.
A graph is said to be a function if the vertical line drawn does not intersect the graph more than one point.
Meaning of vertical line test.
More about vertical line test.
States that if a vertical line intersects the graph of the relation more than once then the relation is a not a function.
If the graph of a function can only have one output for each unique input then relation is function otherwise not.
That is every x value of a function must be paired to a single y value.
If you think about it the vertical line test is simply a restatement of the definition of a function.
What does vertical line test mean.
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.
In mathematics the vertical line test is a visual way to determine if a curve is a graph of a function or not.
Vertical line test is generally done by using a ruler.
