Functions & Relations

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, typically written in the form (x, y).

Front

What does the x-coordinate represent in a coordinate plane?

Back

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

Front

What does the y-coordinate represent in a coordinate plane?

Back

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

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What is the range of a relation?

Back

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

Front

What is a mapping diagram?

Back

A mapping diagram visually represents a relation by showing how each input is paired with an output.

Front

What is the domain of a relation?

Back

The domain of a relation is the set of all possible input values (x-values) that can be used in the relation.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input is associated with exactly one output.

Front

How do you identify a function from a set of ordered pairs?

Back

A set of ordered pairs represents a function if no two pairs have the same first element (x-value).

Front

What is the x-axis?

Back

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