Graphing and Solving Quadratic Inequalities

  • 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.
