BIG MATH

output

The result of substituting a value into a function.

domain

The set of x-coordinates in a relation.

range

The set of y-coordinates in a relation.

zeros

The x-intercepts of the graph of a function; the points for which f(x)=0.

input

A value substituted for an x-value in a function.

mapping

illustration of how each element of the domain is paired with an element in the range

vertical line test

If any vertical line passes through no more than one point of the graph of a relation, then the relation is a function.

Origin

A fixed point from which coordinates are measured.

Arithmetic Sequence Formula

A formula used to find the nth number of an arithmetic sequence

arithmetic sequence

A numerical pattern that increases or decreases at a constant rate or value. The difference between successive terms of the sequence is constant.

Coordinate Plane

A plane that is divided into four regions by a horizontal line called the x-axis and a vertical line called the y-axis.

Quadrants

Four regions into which a coordinate plane is divided by the x-axis and the y-axis

continuous graph

a graph made up of connected lines or curves

discrete graph

a graph made up of unconnected points

Ordered Pair

a pair of numbers used to locate a point on the coordinate plane

function

a relation in which each element of the domain is paired with exactly one element of the range

relation

a set of ordered pairs

function notation

a way to name a function that is defined by an equation

common difference

the difference between consecutive terms of an arithmetic sequence

x-coordinate

the first number in an ordered pair

X-axis

the horizontal number line in a coordinate plane

y-coordinate

the second number in an ordered pair

Y-axis

the vertical number line in a coordinate plane
