Watch this tutorial and learn about the vertical line test.

What is vertical line test for a function. Vertical line test is helpful to find if the given equation represents a function or not. Is a way to determine if a relation is a function. What is the vertical line test for functions?

In other words, in order for a graph to be a function, no perfectly vertical line can cross its graph more than once. If each line crosses the graph just once, the graph passes the vertical line test. Use the vertical line test to identify a function by:

It explains how to tell if a graph represents a function. What is the vertical line test? Vertical line test for functions this is a tool which can be used to test whether the given graph represents a function or not.

If we can draw any vertical line that intersects a graph more than once, then the graph does not define. Not every curve in the coordinate plane can be the graph of a function. The vertical line test is a test to determine if a relation or its graph is a function or not.

Vertical line test for a function: If a vertical line can cross a graph more than once, then the graph does not pass the. Using the vertical line test, you can figure out if a graph is a function or not.

The vertical line test is a way for us to tell visually if a given curve or relation is a function or not. A function is an equation that relates elements from two sets {eq}x {/eq} and {eq}y {/eq} (which are not necessarily distinct sets; Functions are equations that pass the vertical line test.
