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) for which the relation is defined.

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 the input values in the domain.

How can you visually identify the domain and range from a graph?

Back

The domain can be identified by the x-values that the graph covers, while the range can be identified by the y-values that the graph covers.
