What is the Domain of a Relation?

In this domain and range instructional activity, students write the definitions for relation, function, domain and range. They then find the domain and range of 7 sets of ordered pairs. Finally, students answer 4 questions regarding...

Eighth and ninth graders solve and graph 24 different problems that include completing input/output tables and graphing the pairs. First, they find the missing values for each table and write the rule for x. Then, students write the...

In this graphs worksheet, students solve and complete 15 various types of problems. First, they determine the range of the function of the graph shown and write in interval notation. Then, students find the domain of the function in the...

You can learn to graph as well as a calculator using calculus. The lesson introduces using derivatives to find critical points needed to graph polynomials. Pupils learn to find local maximums and minimums and intervals of increase and...

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...

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.

We look at several different examples of functions and see what their domain is. Sal writes the domain in a set notion and shows how different functions can have different input values that cause them to be undefined.

Provides examples and a video lesson that illustrates how to graph a linear equation. [1:33]

The teacher illustrates several ways to look at what the domain is in a set of numbers. Input, output, table, graphs, and diagrams are a few of the ways in which she illustrates the meaning of domain.

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...
