States that if a vertical line intersects the graph of the relation more than once then the relation is a not a function.
Example of vertical line test in math.
A relation is a function if there are no vertical lines that intersect the graph at more than one point.
The vertical line test.
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.
Terms and formulas from algebra i to calculus.
That is every x value of a function must be paired to a single y value.
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.
If you think about it the vertical line test is simply a restatement of the definition of 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.
More about vertical line test.
If the vertical line passes through at least two points on the graph then an element in the domain is paired with more than 1 element in the range.
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.
If the graph of a function can only have one output for each unique input then relation is function otherwise not.
Vertical line test a method used to check whether or not a relation is a function.
Vertical lines help determine if a relation is a function in math.
The slope of a vertical line is undefined because the denominator of the slope the change in x is zero.

In order to be a function each x value can only be paired with exactly one y value.
The graphs of functions can be straight lines or segments curves or even just a set of points.
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.
The equation of a vertical line always takes the form x k where k is any number and k is also the x intercept.
Is a way to determine if a relation is a function.

A vertical line is drawn across the edge of the ruler from one end of the x axis to the other end.
The equation of a vertical line does not have a y intercept since a vertical line never crosses the y axis.
