When graphing the solutions of an inequality What does a parenthesis signify what does a bracket signify?

How do you solve inequalities by graphing?

There are three steps:

1. Rearrange the equation so "y" is on the left and everythingelse on the right.
2. Plot the "y=" line (make it a solid line for y≤ ory≥, and a dashed line for y< or y>)
3. Shade above the line for a "greater than" (y> or y≥)or below the line for a "less than" (y< or y≤).
