Interval Notation (, ) ; (, ]; [, ); [, ]

Inclusive or not… Brackets include the number in the solution set Parenthesis signify the number is not part of the solution set Infinity is not a specific number and is always labeled with a parenthesis When a solution set is a compilation of parts of a number line then we use the union symbol
