RELATIONS

Front

What is a relation in mathematics?

Back

A relation is a set of ordered pairs, typically defined as a relationship between two sets.

Front

What is the domain of a relation?

Back

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

Front

What is the range of a relation?

Back

The range of a relation is the set of all possible output values (y-coordinates) that result from the relation.

Front

What is an ordered pair?

Back

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

Front

What does the x-coordinate represent in an ordered pair?

Back

The x-coordinate represents the horizontal position of a point on a graph.

Front

What does the y-coordinate represent in an ordered pair?

Back

The y-coordinate represents the vertical position of a point on a graph.

Front

What is the origin in a coordinate system?

Back

The origin is the point where the x-axis and y-axis intersect, represented as (0, 0).

Front

How do you identify the domain from a graph?

Back

The domain can be identified by looking at the x-values that the graph covers.

Front

How do you identify the range from a graph?

Back

The range can be identified by looking at the y-values that the graph covers.

Front

What is a mapping in mathematics?

Back

A mapping is a function that associates each element of a set with an element of another set.
