In this lecture you will learn how to Graph and Solve Quadratic Inequalities. Professor Fraser will begin with Graphing Quadratic Inequalities such as Linear Inequalities and Quadratic Inequalities. Then, you will move onto Solving Quadratic Inequalities before the four video examples.
Use the same
techniques that were used to solve linear inequalities. Follow the
conventions about how to draw the boundary curve (solid line or
dotted line) and use a test point to determine the region that is
the solution set. Sometimes, more than one test point must be used.
