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.

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 the input values in the domain.

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

Back

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

Front

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

Back

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

Front

What is the domain of the function {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

The domain is {-4, 0, 1, 2}.

Front

What is the range of the function {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

The range is {-4, -3, 1}.

Front

What does the notation -3 < x ≤ 3 represent?

Back

This notation represents the domain of a function where x is greater than -3 and less than or equal to 3.

Front

What does the notation -3 ≤ y < 1 represent?

Back

This notation represents the range of a function where y is greater than or equal to -3 and less than 1.

Front

What is the significance of the notation y ≥ 0 in a range?

Back

This notation indicates that the range includes all values of y that are greater than or equal to 0.

Front

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.
