Exercise 10 Page 56

For inequalities on a number line, what does it mean when a point is open or closed?

Practice makes perfect
To graph an inequality on a number line, we need to make note of two things: the direction of the inequality and whether it is strict.

v ≥ sqrt(36) Observing the given inequality, we see that all values of v are greater than or equal to sqrt(36)=6. This means that the solution set lies to the right of 6 on a number line. Furthermore, the inequality symbol indicates that v=6 is a solution, which we will mark with a closed circle on the number line at 6.
