Question
Express the following sets in the interval notation:(i) Set of real numbers between -3 and 5, inclusive.(ii) {๐ โฃ ๐ > ๐}(iii) Set of all real numbers ๐ such that ๐ is greater than 2 or ๐ is less than -5.(iv) {๐ โฃ ๐ โค โ๐}(v) {๐ โฃ โ๐ โค ๐ < ๐}
Solution
(i) The set of real numbers between -3 and 5, inclusive, can be expressed in interval notation as [-3, 5].
(ii) The set {๐ โฃ ๐ > ๐} can be expressed in interval notation as (0, โ).
(iii) The set of all real numbers ๐ such that ๐ is greater than 2 or ๐ is less than -5 can be expressed in interval notation as (-โ, -5) U (2, โ).
(iv) The set {๐ โฃ ๐ โค โ๐} can be expressed in interval notation as (-โ, -1].
(v) The set {๐ โฃ โ๐ โค ๐ < ๐} can be expressed in interval notation as [-3, 2).
