Interval notation: used for representing the domain and range, solutions that are written as inequalities, and number line solutions.
Close notation: Is used when there is an equal sign in the domain for example: a⪬x≥b, you would write the following as [a,b]
Open notation: is used when there is no equal sign in the domain for example: a﹤x﹥b, you would write the following as (a,b)
