The solution set in interval notation can be written in two ways. The first one is the closed interval . In a closed interval, the endpoints are included in the solution and this is enclosed by square brackets. This is given in the form [ a, b]. On the other hand, the set notation is { x ∣ a ≤ x ≤ b }.

Some General Tips. The smaller value of the interval goes first and the larger value of the interval goes second; the two values are separated by a comma. Parentheses indicate an open interval and square brackets a closed interval, although you can also have a mixture of the two, giving a half closed or half open interval.
