Virtual Nerd: Use the Vertical Line Test to Figure Out if a Graph Is a Function

Relations, and functions, and line tests, oh my! An instructional slideshow demonstrates the definitions of a relation, a function, and the domain and range of a relation. Viewers then learn how to use mappings and vertical...

Relationships can be good or bad, but functional relationships are the best! The video demonstrates relationships in a table or graph and what makes their qualities functional. Have your learners review functions and then go through a...

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...

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...

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]

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.

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...

Students learn how to use the vertical line test to determine if a relation is a function. A video tutorial explores the algebra topic.
