Unit 1: Introduction to Functions
Lesson 3 of 13

Objective: SWBAT identify if a relation is a function or not, and explain that there must be exactly one output for each input, and apply the Vertical Line Test for proof.

Big Idea: This lesson introduces functions with the school's vending machine, and uses a Frayer Model to summarize the different representations of relations and functions.
