Domain and Range

Front

What is the definition of Domain in a relation?

Back

The domain of a relation is the set of all possible input values (x-values) that can be used in the relation.

Front

What is the definition of Range in a relation?

Back

The range of a relation is the set of all possible output values (y-values) that result from using the domain values in the relation.

What does it mean when we say the domain is restricted?

Back

It means that not all possible x-values are included in the domain due to certain conditions or limitations.

Front

How do you find the domain of a function given its graph?

Back

Look for the x-values that the graph covers from left to right.
