Empty set interval notation
WebInterval Notation Interval notation is a way of writing subsets of the real number line . A closed interval is one that includes its endpoints: for example, the set { x -3 ≤ x ≤ 1} . To write this interval in interval notation, we use closed brackets [ ]: [-3,1] An open interval is one that does not include its endpoints, for example, { x -3 < x < 1} . WebAn Interval is all the numbers between two given numbers. Showing if the beginning and end number are included is important There are three main ways to show intervals: …

Common notations for the empty set include "{}", "", and "∅". The latter two symbols were introduced by the Bourbaki group (specifically André Weil) in 1939, inspired by the letter Ø in the Danish and Norwegian alphabets. In the past, "0" was occasionally used as a symbol for the empty set, but this is now considered to be an improper use of notation.
