Relations, Domains, and Ranges MI2

Front

What is the domain of a relation?

Back

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

Front

What is the range of a relation?

Back

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

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers (x, y) that represents a point in a coordinate system.

Front

What is a relation in mathematics?

Back

A relation is a set of ordered pairs, where each pair consists of an input and an output.

Front

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

Back

To find the domain, list all the first elements (x-values) of the ordered pairs.

Front

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

Back

To find the range, list all the second elements (y-values) of the ordered pairs.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input (x-value) is associated with exactly one output (y-value).

Front

If the ordered pairs are (1, 2), (3, 4), (5, 6), what is the domain?

Back

The domain is {1, 3, 5}.

Front

If the ordered pairs are (1, 2), (3, 4), (5, 6), what is the range?

Back

The range is {2, 4, 6}.

Front

What does it mean if a relation is not a function?

Back

It means that at least one input (x-value) is associated with more than one output (y-value).
