# Chapter 1: Analyzing Functions

Difficulty Level:

**At Grade**Created by: CK-12

## Introduction

This section focuses on investigating functions both graphically and mathematically.

Lessons in this section specifically teach:

- Identifying the maximum and minimum values of a function both by investigating a graph and using Algebra.
- Identifying the rate of change of a function
- Understanding the concept of limit
- Recognizing and using asymptotes
- Understanding and using function notation
- Parent functions and the use of transformations
- Recognizing the difference between functions and relations
- Understanding the concept of intervals and the use of interval notation

By the time you finish this section, you should have a fresh understanding of what functions are, and how to manipulate them to find specific bits of information.
