Lesson 1: Rational Functions

Rational functions are an important topic in Algebra 2. In this lesson, we will explore various aspects of rational functions, including asymptotes, simplifying them, and graphing them. By the end of this lesson, You will have a solid understanding of rational functions and be able to Apply your knowledge to solve problems.

2.1 Introduction to Rational Functions

We will start this lesson by introducing the concept of rational functions. A rational function is a function that can be expressed as the quotient of two polynomials. We will discuss the numerator and denominator of rational functions and their respective roles in determining the function's behavior.

2.2 Asymptotes

Asymptotes play a crucial role in understanding the behavior of rational functions. In this section, we will explore different types of asymptotes, including horizontal asymptotes and vertical asymptotes. We will learn how to identify and interpret asymptotes from the equation of a rational function.

2.2.1 Horizontal Asymptotes

Horizontal asymptotes are straight lines that the graph of a rational function approaches as the x-values increase or decrease without bound. We will discuss the conditions for the existence of horizontal asymptotes and learn how to find them algebraically.

2.2.2 Vertical Asymptotes

Vertical asymptotes are vertical lines that the graph of a rational function approaches as the x-values approach a certain value. We will learn how to find the vertical asymptotes of a rational function and interpret their significance in understanding the behavior of the function.

2.3 Simplifying Rational Functions

Simplifying rational functions is an essential skill that allows us to analyze and manipulate these functions more easily. We will discuss techniques for simplifying rational functions, including factoring the numerator and denominator, canceling common factors, and reducing the function to its simplest form.
