What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, typically written as (x, y).

Front

In the ordered pair (4, 9), what is the x-coordinate?

Back

4

Front

In the ordered pair (4, 9), what is the y-coordinate?

Back

9

Front

What is the definition of the domain in a relation?

Back

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

Front

What is the definition of the range in a relation?

Back

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

Front

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

Back

A relation is a function if each input (x-value) is associated with exactly one output (y-value).

Front

What is the difference between domain and range?

Back

Domain refers to the set of x-values, while range refers to the set of y-values in a relation.

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

What is a mapping in mathematics?

Back

A mapping is a way to show how each element of a domain is paired with an element in the range.

Front

What is the x-axis in a coordinate system?

Back

The x-axis is the horizontal line in a coordinate plane where y=0.
