The solutions are all real numbers less than 2. An open dot is used in the graph to indicate 2 is not a solution. EXAMPLE 1 Graph simple inequalities a. Graph x < 2.
The solutions are all real numbers greater than or equal to –1. A solid dot is used in the graph to indicate –1is a solution. EXAMPLE 1 Graph simple inequalities b. Graph x ≥ –1.
The solutions are all real numbers that are greater than –1 and less than 2. EXAMPLE 2 Graph compound inequalities a. Graph –1 < x < 2.
The solutions are all real numbers that are less than or equal to –2 or greater than 1. EXAMPLE 2 Graph compound inequalities b. Graph x ≤ –2 orx > 1.
Graph the inequality. 1. x > –5 The solutions are all real numbers greater than 5. An open dot is used in the graph to indicate –5is not a solution. for Examples 1 and 2 GUIDED PRACTICE
Graph the inequality. 2. x ≤ 3 The solutions are all real numbers less than or equal to 3. A closed dot is used in the graph to indicate 3is a solution. for Examples 1 and 2 GUIDED PRACTICE
