Domain and Range Teacher Resources

After defining a simple function from a word problem, this video shows how to find the domain and range of that function. The goal is to reinforce the definitions of domain and range with a concrete example.

A straightforward explanation of domain and range. The domain of a set of coordinates are the x-values, and then range are the y-values of the set.

After defining a simple function from a word problem, a short video shows how one could find the domain and the range of that function. The instruction reinforces the definitions of domain and range with a concrete example.

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...

If your students can't remember the difference between domain and range, then here's a video for you. Scholars learn to identify the domain and range of nine basic function types: constant, linear, absolute value, quadratic, cubic,...

Calculating domain and range of a function is a challenge! A helpful video shows learners the steps to finding the domain and estimating the range algebraically. Scholars understand the relationship of the domain and range. 

Introduce the concept of domain and range with a video that starts with the formal definitions of the domain and range and moves on to the practical descriptions used to determine them. The presentation explains how to find the domain...

The abstract notion of domain and range can be troublesome. A math lesson explains the concept of determining domain and range from a graph. The instructor makes clear connections between the graph and the numeric values. There are 29...

There's no restriction to how much your class can learn about domain and range. Users of an interactive adjust the radius of a circle to see its effects on the area. They note how restrictions in the domain (radius) relate to...

Graphs are useful for many things, including seeing how much money you can make. Individuals create a graph of earnings from a job based on the number of hours. They determine the domain and range of the graph and answer challenge...

Help algebra learners relate a real-life function that happens at the Oakland Coliseum every time the Raiders play. The resource states that the revenue of the Oakland Raiders home games is a function of the number of seats sold and the...

Take your kids on a tour of graphing rational functions. Using this TI lesson, high schoolers identify the end behavior of their functions. They find the domain and range, describe end behavior, and look at asymptotes and restrictions of...

In this algebra worksheet, students state the domain and range of various functions and equations. There are five questions and some are multiple choice questions.

A straightforward explanation of domain and range. The domain of a set of coordinates are the X-values, and then range are the Y-values of the set.

Finding the domain and range of the inverse of a relation can be tricky, unless you know the correct steps! It's not that complicated. Watch this video and see how the instructor does the inverse of a relation before writing the domain...

Using this worksheet, pupils graph 11 simple rational functions. They also find asymptotes, domain, and range for each function. The solutions are provided.

Take the work out of worksheets and use these problems and worked-out answer key as a resource. The problems reinforce skills in domain and range, identifying graphs, and even and odd functions.

How do you identify the domain and range of the function? As learners find out it's as easy as creating a graph. They'll identify the domain and range of a relation from its graph, write symbolic expressions describing the relationship...

Your class will grasp the concept of domain-and range on a graph by using their TI navigator to graph their lines. They observe the effect of a function and non-functions based on the domain and range.

Have your class find the domain and range for each function. Students graph equations using the TI. They find all the x and y values as they relate to the domain and range.

Moving the graph of a function obviously changes its domain and range. Scholars adjust the location of a graph in an interactive coordinate plane. The interactive automatically updates and displays the domain and range to show how it...

Take a deeper dive into the notation of a function. The video presentation uses grocery store prices as an example to explain the concept of a function. Pupils determine whether mappings are functions or not and find the domain and...

In this domain and range worksheet, students examine functions and identify the range of a function.  They find the maximum and minimum value of a function.  This two-page worksheet contains 7 multiple-choice problems.  Answers are...
