Domain and Range DN 3.1

Front

What is a relation in mathematics?

Back

A relation is a set of ordered pairs, typically representing a relationship between two sets of values.

Front

What does the domain of a relation represent?

Back

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

Front

What does the range of a relation represent?

Back

The range of a relation is the set of all possible y-values (outputs) that result from the relation.

Front

Given the relation {(0, 1), (1, 2), (2, 2), (3, 4)}, what is the domain?

Back

The domain is {0, 1, 2, 3}.

Front

Given the relation {(0, 1), (1, 2), (2, 2), (3, 4)}, what is the range?

Back

The range is {1, 2, 4}.

Front

How do you determine the domain from a graph?

Back

To determine the domain from a graph, identify all the x-values that the graph covers.

Front

How do you determine the range from a graph?

Back

To determine the range from a graph, identify all the y-values that the graph covers.

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

Back

The range is {1, 2}.

Front

What is the significance of ordered pairs in a relation?

Back

Ordered pairs indicate the relationship between the first element (x-value) and the second element (y-value) in a relation.
