Answer 1

Answer:

In mathematics, particularly in order theory, an upper bound or majorant of a subset S of some preordered set (K, ≤) is an element of K which is greater than or equal to every element of S. Dually, a lower bound or minorant of S is defined to be an element of K which is less than or equal to every element of S.
