The vertical line test supports the definition of a function.
Example of vertical line test in math.
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.
A vertical line is drawn across the edge of the ruler from one end of the x axis to the other end.
A vertical line test is a visual way to determine if the graph of a relation is a function using a vertical line.

But not all graphs represent functions.
That is every x value of a function must be paired to a single y value.
Terms and formulas from algebra i to calculus.
Examples of vertical line test.
Horizontal line test one to one function.
States that if a vertical line intersects the graph of the relation more than once then the relation is a not a function.
A curve in the xy plane is the graph of a function x if and only if no vertical line intersects the curve more than once.
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 equation of a vertical line always takes the form x k where k is any number and k is also the x intercept.
Using vertical line test the graph given represents a function as the vertical line drawn intersects the graph at only one point.
The slope of a vertical line is undefined because the denominator of the slope the change in x is zero.
Vertical lines help determine if a relation is a function in math.
If the graph of a function can only have one output for each unique input then relation is function otherwise not.
The vertical line test is a visual test that you can use to quickly check and see if a graph represents a function.
Vertical line test is generally done by using a ruler.
The graphs of functions can be straight lines or segments curves or even just a set of points.
The reason for the truth of the vertical line test can be seen in figure 13.

A test use to determine if a relation is a function.
More about vertical line test.
The equation of a vertical line does not have a y intercept since a vertical line never crosses the y axis.
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.
Vertical line test a method used to check whether or not a relation is a function.
