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 (or 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 (or y-values) that result from using the domain values in the relation.

Front

How do you determine the domain from a set of ordered pairs?

Back

To determine the domain from a set of ordered pairs, list all the unique x-values from the pairs.

Front

How do you determine the range from a set of ordered pairs?

Back

To determine the range from a set of ordered pairs, list all the unique y-values from the pairs.

Front

What is the domain of the relation {(-5, 4), (-1, 0), (3, -1), (3, 5)}?

Back

The domain is {-5, -1, 3}.

Front

What is the range of the relation {(-5, 4), (-1, 0), (3, -1), (3, 5)}?

Back

The range is {4, 0, -1, 5}.

Front

What is the domain of the relation shown in the table: { (6, 1), (18, 2) }?

Back

The domain is {6, 18}.

Front

What is the range of the mapping { (6, 1), (18, 2) }?

Back

The range is {1, 2}.

Front

How can you represent the domain and range of a function graphically?

Back

The domain can be represented on the x-axis and the range on the y-axis of a graph.

Front

What is the importance of identifying the domain and range in real-world applications?

Back

Identifying the domain and range helps to understand the limitations and possible values of a function in real-world scenarios.
