ordered pair

shows the relationship between two elements, written in a specific order using parentheses notation and a comma separating the two values.

Domain

The set of all inputs for a function "x-value"

function

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

relation

a set of pairs of input and output values

finite set

a set with a definite number of elements

infinite set

a set with an unlimited, or infinite, number of elements

mapping

a visual- representation of a relation in which an arrow associates each input with its output (input → output)

function notation

an equation in the form of 'f(x)=' to show the output value of a function, f, for an input value x

f(x) = y

domain is 'x' Range is 'f(x)' and 'y'
