In this module you will review functions

Module 2 - Lesson 2

There are a few ways to tell if a relation is a function:Mapping DiagramsChecking the x-termsVertical Line Testand more!Every x-value must have ONE y-value.

Lesson 2 - Functions

This graph is a function because it passes the vertical line test where each vertical line only passes through one point

This relation is not a function because 2 is paired with more than one y-value.

This mapping is a function because each x-value maps to exactly ONE y-value.

This is a Function

This is NOT a Function
{(2, 4), (4, 1), (2, 6), (1, 1)}
