How does the vertical line test help you decide if the graph of an equation is a function? The instructor draws a graph and then draws the line of the equation. She demonstrates how to use the vertical line test to determine if the graph...

Is the graph of the equation a function? Use the vertical line test to answer this question. The definition states that the vertical line can pass through the graph of the line no more than one time. The teacher demonstrates exactly what...

There's no easier test than the vertical line test. Learners drag a vertical line across the graphs of several relations in an interactive. They answer a set of challenge questions that focus on whether the graphs represent functions.

Connect the points to create a function. Using points given by the applet, pupils try to connect them to create a line that would pass the vertical line test. The resource keeps track of the number of sets the learner is able to identify...

How does the vertical line test help you decide if the graph of an equation is a function? The instructor draws a graph and then draws the line of the equation. She demonstrates how to use the vertical line test to determine if the graph...

What do vertical lines have to do with functions? Individuals slide a vertical line through four different graphs. They use that vertical line test to determine if the graphs represent functions.

Using the vertical line test, you can figure out if a graph is a function or not. Watch this tutorial to learn about the test. [3:30]

To find the equation of a vertical line you need to use x=b to determine the equation. This tutorial explains the use of formula x=b to find a value for an unknown y. The explanation of this concept is rushed making this tutorial only...

Draw a graph, label the units, plot the given point, then draw a straight line up and down through the given point. That is now the graph of a vertical line through a given point.

Learn about the vertical line test for functions by trying to connect points in the plane to build a function. When you have connected all of the points, you will be told if your graph is a valid graph of a function.
