#### How Do You Use the Vertical Line Test to Figure Out if a Graph is a Function?

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...

Lesson Planet

#### What's the Vertical Line Test?

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...

Lesson Planet

#### Vertical Line Test

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...

#### Identify Functions and the Vertical Line Test: The Vertical Line Test

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.

Lesson Planet

#### Which Functions Pass the Vertical Line Test?!!

What is a function? Teachers have been asking pupils this question from the time they started their algebra careers. A helpful video walks through the process of using the vertical line test to determine a function while showing various...

Lesson Planet

#### Vertical Line Test: Exploration

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.

Lesson Planet

#### Functions and the Vertical Line Test

Students explore the concept of functions. In this function lesson plan, students determine if the graph is a function by using the vertical line test. Students use an applet to explore the vertical line test on a variety of graphs.

Lesson Planet

#### Domain and Range

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 line tests to...

Lesson Planet

#### Functions

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...

Lesson Planet

#### Algebraic Functions: Vertical Line Test

To be (a function) or not to be (a function). An easy-to-use interactive has pupils drag a vertical line onto several graphs to determine if they represent functions. Some challenge questions assess understanding of this idea.

Lesson Planet

#### Lesson 9: Linear Functions

High schoolers identify linear functions. They identify ordered pairs, perform a vertical line test, and examine functions described by equations. Students plot functions on a coordinate plane.

Lesson Planet

#### Identifying the Graphs of Functions

An assessment provides four graphs of relations. Pupils identify which of the four are functions and provide an explanation of why. They then explain the reasoning behind the vertical line test if they used it to find the functions.

Lesson Planet

#### Functions and the Vertical Line Test

Students examine functions and function notation. They use computer activities to discover how to graph functions, and conduct a vertical line test. Students describe spatial relationships using coordinate geometry.

Lesson Planet

#### What Are Functions?

Setup the idea of functions for the class. Using sets, the presentation introduces the concept of a function. The initial example uses a general function but then moves on to equations as functions. The video provides an example of an...

Lesson Planet

#### Functions

One in, one out is what functions are about in a video explaining the rules and qualities of these relationships. Have your learners practice with ordered pairs, tables, mapping, and graphs, deciphering whether or not those relationships...

Lesson Planet

#### What is a Function?

Students investigate websites that have been linked in a TrackStar to study the difference between domain and range. They examine whether a relation is a function and apply the vertical line test on a graphical representation while using...

Lesson Planet

#### Circles and Functions

Scholars analyze the graph of a circle to determine what portion they should remove to make the resulting graph a function. The pupils mark the section on the graph and explain why what is left is a function.

Lesson Planet

#### Functions - Intro and Inverses

Define the terms domain, range, function, vertical limit test, and linear function notation with your class. They can then, graph several equations applying the vertical line test to determine which are and which are not functions, write...

Lesson Planet

#### Calculus - Functions

An understanding of the basics of a function is key to success in upper-level math courses! A video describes in detail the important aspects of functions including domain, range, combinations, compositions, and vertical line test.

Lesson Planet

#### What is a Function?

In this function worksheet, students explore the properties of a function. They are given equations and graphs to determine if the equation is a function. Explanations and examples are provided. This eight-page worksheet contains ten...

#### Functions and Their Graphs

Use a worksheet to go over the basic concepts of relations and functions. Included are clear definitions and examples of relations, domain and range, and functions and the vertical line test. However, the problems are pretty basic. A...

Lesson Planet

#### Functions

What makes a function a function? Learn the criteria for a relation defined as a function both numerically and graphically. Once young mathematicians define a function, they use function notation to evaluate it.
