Function Vocabulary

the set of all possible input values of a function

• range

• domain

• function

• vertical line test

an input-output relationship that has exactly one output for each input

• function table

• relation

• function

• y-intercept

a table of ordered pairs that represent solutions of a function

• function table

• function

• slope

• domain

the equation of a line in the form of y – y₁ = m(x – x₁), where m is the slope and (x₁,y₁) is a specific point on the line

• y-intercept

• slope intercept form

• rate of change

• point-slope form

the set of all possible output values of a function

• range

• rate of change

• domain

• function

a ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable

• rate of change

• slope

• relation

• vertical line test

a set of ordered pairs

• slope

• slope intercept form

• relation

• function

a measure of the steepness of a line on a graph; the rise divided by the run

• vertical line test

• range

• domain

• slope

a linear equation written in the form y = mx + b, where m represents slope and b represents the y-intercept

• slope intercept form

• slope

• relation

• function

a test used to determine whether a relation is a function. If any vertical line crosses the graph of a relation more than once, the relation is not a function.
