WebFeb 6, 2024 · 1. Does the sign chart for any given polynomial or rational function always alternate? Explain and illustrate your answer with some examples. 2. Write down your own steps for solving a rational inequality and illustrate them with an example. Do your steps also work for a polynomial inequality? Explain. Answer 1: 1. Answer may vary WebSolving Polynomial Inequalities Note: This material is to supplement Section 3.6. Unlike linear inequalities, polynomial inequalities cannot always be solved with just algebra, and other techniques will need to be used. We will learn to solve inequalities once they are of the form where one side of the inequality is a polynomial and the other is 0.
