Interval Notation
... We basically use two symbols: parentheses ( ) and brackets [ ]: ( ) is used for less than, < , or greater than, >. This means that specified values for a or b are not included. [ ] is used for less than or equal to, ≤, or greater than or equal to, ≥. This means that specified values for a or b are i ...
