Beyond that, set notation uses descriptions: the interval (-3,5] is written in set notation as read as " the set of all real numbers x such that ." WebInterval notation is a method to represent an interval on a number line. In other words, it is a way of writing subsets of the real number line. An interval comprises the numbers lying between two specific given numbers. For example, the set of numbers x satisfying 0 ≤ x ≤ 5 is an interval that contains 0, 5, and all numbers between 0 and 5. irish players in england cricket team
