Representing Relations Review

Front

What is the definition of a relation in mathematics?

Back

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

Front

What is the domain of a relation?

Back

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

Front

What is the range of a relation?

Back

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

Front

How do you identify the coordinates of a point on a graph?

Back

Coordinates are identified as (x, y), where x is the horizontal position and y is the vertical position.

Front

What does the point (0, 0) represent on a graph?

Back

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

Front

What is the purpose of a mapping diagram?

Back

A mapping diagram visually represents the relationship between the domain and range of a relation.

Front

How can you determine if a relation is a function?

Back

A relation is a function if each input (x) corresponds to exactly one output (y).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a graph, written as (x, y).

Front

What does the term 'vertical line test' refer to?

Back

The vertical line test is a method to determine if a graph represents a function; if a vertical line intersects the graph at more than one point, it is not a function.

Front

What is the significance of the x-axis in a coordinate plane?

Back

The x-axis is the horizontal line in a coordinate plane, representing the set of all x-coordinates.
