Unformatted text preview: brackets [ ] you know that the inequality includes the number. When intervals are in parentheses ( ) you know the interval does not include the number. So looking at (4,10) we would write the inequality out as 4<x<10. So the number line would be exactly the same but with one exception: circles are not closed in because the solution set does not include the intervals given in the equation. Now for one more example: [4,10) you see you have one bracket [ and one parentheses ). So the inequality would be written out as 4 ≤ x < 10. So when graphing this inequality you would close the circle for 4 because this number is included in the solution set, but you would leave the circle open for the number 10 because the number is not included....
