Exercise 38 Page 59

Which side of the number line should be shaded according to the inequality?

Inequality: n≥-2
Graph:

Practice makes perfect
Let's begin by interpreting the given set-builder notation. {n | n ≥ -2} n is greater than or equal to -2

This solution set can be written as an inequality. n ≥ -2 To graph this inequality, we place a closed circle at -2 on a number line. Since n is greater than -2, the solution set includes all numbers that are above -2. Therefore, we should shade everything to the right of the closed circle.
