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 math.
In order to be a function each x value can only be paired with exactly one y value.
A test use to determine if a relation is a function.
If the graph of a function can only have one output for each unique input then relation is function otherwise not.
A graph is said to be a function if the vertical line drawn does not intersect the graph more than one point.
Horizontal line test one to one function.
What does vertical line test mean.
If you think about it the vertical line test is simply a restatement of 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.
In mathematics the vertical line test is a visual way to determine if a curve is a graph of a function or not.
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.
