If I represent the closed end as [ or ] and the open end as ( or ), then your nuymber line would look like the following: ``` ------------------------------------------------------------------------------ -4 -3 -2 -1 0 1 2 3 4 5 6 7 (-------------------------------------] ``` The reference tells you to use an open circle for ( and a close circle for ] as long as your audience knows the symbols you are using, and what they mean, you can use just about anything to represent closed end or open end. not that in interval notation, this would be shown as (-3,6].
