Functions and Their Vocabulary

a pair of numbers or two coordinates used to locate any point on a coordinate plane, written in the form (x,y)

• Domain

• Range

• Origin

• Ordered pair

Four regions into which the x- and y-axis separate the coordinate plane. The four regions are numbered (I, II, III, IV)

• Ordered pair

• coordinate plane

• quadrants

• mapping

a set of ordered pairs

• relation

• mapping

• function

• function notation

A relation in which each element of the domain is paired with exactly one element of the range. This is typically generated by some rule.

• mapping

• vertical line test

• relation

• function

The set of all first coordinates (or x-values) of a relation or function

• ordered pair

• domain

• range

• zeros

A plane divided into four regions by horizontal and vertical number lines that is used for graphing

• quadrants

• coordinate plane

• domain

• range

Given a graph, this test is used to determine whether a relation is a function

• horizontal line test

• function notation

• mapping

• Vertical line test

A graph consisting of connected lines or curves

• discrete graph

• continuous graph

The set of all second coordinates (or y-values) of a relation or function.

• zeros

• range

• origin

• domain

A way of renaming an equation by replacing y with f(x)

• Function notation

• Vertical line test

• Arithmetic sequence

• mapping
