Front

Identify the domain of a relation.

Back

The domain of a relation is the set of all possible input values (x-values) from the ordered pairs.

Front

Identify the range of a relation.

Back

The range of a relation is the set of all possible output values (y-values) from the ordered pairs.

Front

What does it mean for a relation to be a function?

Back

A relation is a function if no x-value is repeated with different y-values.

Front

What is the domain of the relation given the ordered pairs (11, 60), (12, 63), (12, 66), (13, 64), and (14, 67)?

Back

{11, 12, 13, 14}.

Front

What is the range of the mapping given the outputs {1, 2, 4}?

Front

If a relation has the ordered pairs (2, 3), (2, 4), (3, 5), is it a function?

Back

No, because the input 2 has two different outputs (3 and 4).

Front

What is the difference between domain and range?

Back

Domain refers to the set of input values (x-values), while range refers to the set of output values (y-values).
