A vertical line test is a test to see if the graph of a relation represents a function.

Explain what the vertical line test is and how it is used. The vertical line test is a way for us to tell visually if a given curve or relation is a function or not. Try to solve them prior to looking at the answers. Watch this tutorial and learn about the vertical line test.

Draw a vertical line cutting through the graph of a. Of course, if we can find only one value for x that has two or more y values, then we are sure that the relation is not a function. So the idea is, ah, function.

If a vertical line can cross a graph more than once, then the graph does not pass the vertical line test. Here we have selected a simple one from many complicated vertical line test examples for you: In mathematics, the vertical line test is a visual way to determine if a.

Recall that a function can only be a function if every value. For the graphs 2, 3 and 4, it is possible to draw a vertical line. In other words, in order for a graph to be a function, no perfectly vertical line can cross its graph more than once.

Accurate answer to the question explain what the vertical line test is and how it is used. The abscissa shows the domain of the (to be tested) function. Functions are equations that pass the vertical line test.

If you can at any location draw a vertical line that touches the graph in more than one location,. The approach is rather simple. The vertical line test is a test that can be performed on a graph to determine if a relation is a function.
