Question

the interval a<x<b is​

Answer 1

Answer:

In mathematics, a (real) interval is a set of real numbers that contains all real numbers lying between any two numbers of the set. For example, the set of numbers x satisfying 0 ≤ x ≤ 1 is an interval which contains 0, 1, and all numbers in between. Other examples of intervals are the set of numbers such that 0 < x < 1, the set of all real numbers {\displaystyle \mathbb {R} }, the set of nonnegative real numbers, the set of positive real numbers, the empty set, and any singleton (set of one element).
