What is the range of a relation?

Back

The range of a relation is the set of all output values (y-values) that correspond to the input values (x-values).

Front

What is the domain of a relation?

Back

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

What is an ordered pair?

Back

An ordered pair is a pair of numbers (x, y) where 'x' is the first element (x-coordinate) and 'y' is the second element (y-coordinate).

Front

What does the first number in an ordered pair represent?

Back

The first number in an ordered pair represents the x-coordinate.

Front

What does the second number in an ordered pair represent?

Back

The second number in an ordered pair represents the y-coordinate.

What is a relation in mathematics?

Back

A relation is a set of ordered pairs, which can represent a relationship between two sets of values.

Front

What is the difference between a relation and a function?

Back

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

Front

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

Back

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

Front

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

Back

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

What is the notation for the range of a relation?

Back

The range is often denoted as R = {y1, y2, y3, ...} where y1, y2, y3 are the output values.
