# Chapter 3: Functions and Graphs

Difficulty Level:

**Advanced**Created by: CK-12

## Introduction

Here you'll learn the difference between a function and a relation. You will explore both linear and quadratic functions.

## Chapter Outline

- 3.1. The Cartesian Plane
- 3.2. Relations and Functions
- 3.3. Function Notation
- 3.4. Graphs of Linear Functions from Tables
- 3.5. Graphs of Linear Functions from Intercepts
- 3.6. Domain and Range
- 3.7. Graphs of Basic Quadratic Functions
- 3.8. Transformations of Quadratic Functions
- 3.9. Vertex Form of a Quadratic Function

### Chapter Summary

## Summary

You learned what makes a relation a function. You reviewed the Cartesian plane and how to plot points. You learned how to analyze a function's domain and range.

You explored linear functions and how to graph them using a table of values or intercepts. You also explored quadratic functions. You learned how to transform quadratic functions and write the equation of a parabola in vertex form.
