  1. Section 2 Polynomial Inequalities in One Variable

  2. Objective • To graph polynomial inequalities in two variables and to graph the solution set of a system of inequalities.

  3. Graphs of Inequalities • Graph inequalities the same as equations… EXCEPT: • You will decide whether you will draw the graph dashed or solid • You will decide whether you will shade above or below the graph

  4. Types of Lines • You will use a dashed line for great than or less than inequality • You will use a solid line if the inequality can be equal to

  5. Shading of Graphs • You will shade below the graph if the inequality is less than or less than or equal to • You will shade above the graph if the inequality is greater than or greater than or equal to

  6. Examples • Graph the following inequalities

  7. Examples • Graph the following inequality.

  8. Examples • Graph the solution set of the inequalities

  9. Examples • Find all x when Find all (x,y) when
