Here is a correct proof by contradiction. Assume that the natural numbers are bounded, then there exists a least upper bound in the real numbers, call it x, such that n ≤ x for all n. Consider x - 1. Since x is the least upper bound, then x - 1 is not an upper bound; i.e. there exists a specific n such that x - 1 < n. But then, x - 1 < n implies x < n + 1, hence x is not an upper bound. QED This concludes the proof; i.e. there exists no upper bound in the real numbers for the set of natural numbers. P.S. There exists sets in which the set of natural numbers are bounded, but these are not in the real number system.

In mathematics, given a subset S of a totally or partially ordered set T, the supremum (sup) of S, if it exists, is the least element of T which is greater than or equal to any element of S. Consequently, the supremum is also referred to as the least upper bound (lub or LUB). If the supremum exists, it is unique. If S contains a greatest element, then that element is the supremum; otherwise, the supremum does not belong to S (or does not exist). For instance, the negative real numbers do not have a greatest element, and their supremum is 0 (which is not a negative real number).Suprema are often considered for subsets of real numbers, rational numbers, or any other well-known mathematical structure for which it is immediately clear what it means for an element to be "greater-than-or-equal-to" another element. The definition generalizes easily to the more abstract setting of order theory, where one considers arbitrary partially ordered sets.The concept of supremum coincides with the concept of least upper bound, but not with the concepts of minimal upper bound, maximal element, or greatest element. The supremum is in a precise sense dual to the concept of an infimum.add me moshi monsters elydingle1
It is the smallest number, s, such that x <= s for any element, x, of the set; and if e is any number, however small, then there is at least one element in the set such that x > (s - e) : that is, (s - e) is not an upper bound.
Let (B, ≤) be a partially ordered set and let C ⊂ B. An upper bound for C is an element b Є Bsuch that c ≤ b for each c Є C. If m is an upper bound for C, and if m ≤ b for each upper bound b of C, then m is a least upper bound of C. C can only have one least upper bound, and it may not have any at all (depending on B). The least upper bound of a set C is often written as lub C.See related links for more information.
The acronym LUB stands for Least Upper Bound.
The answer depends on the level of accuracy of the value 0.
Lower bound is 17.6 and upper bound is 17.8
Answer: NO Explanation: Let's look at an example to see how this works. A is all rational numbers less than 5. So one element of A might be 1 since that is less than 5 or 1/2, or -1/2, or even 0. Now if we pick 1/2 or 0, clearly that numbers that are greater than them in the set. So what we are really asking, is there a largest rational number less than 5. In a set A, we define the define the supremum to be the smallest real number that is greater than or equal to every number in A. So do rationals have a supremum? That is really the heart of the question. Now that you understand that, let's state an important finding in math: If an ordered set A has the property that every nonempty subset of A having an upper bound also has a least upper bound, then A is said to have the least-upper-bound property In this case if we pick any number very close to 5, we can find another number even closer because the rational numbers are dense in the real numbers. So the conclusion is that the rational number DO NOT have the least upper bound property. This means there is no number q that fulfills your criteria.
A function whose upper bound would have attained its upper limit at a bound. For example, f(x) = x - a whose domain is a < x < b The upper bound is upper bound is b - a but, because x < b, the bound is never actually attained.
The answer is B.
An upper bound estimate is a estimate that is greater than the actual solution.
Here is a correct proof by contradiction. Assume that the natural numbers are bounded, then there exists a least upper bound in the real numbers, call it x, such that n ≤ x for all n. Consider x - 1. Since x is the least upper bound, then x - 1 is not an upper bound; i.e. there exists a specific n such that x - 1 < n. But then, x - 1 < n implies x < n + 1, hence x is not an upper bound. QED This concludes the proof; i.e. there exists no upper bound in the real numbers for the set of natural numbers. P.S. There exists sets in which the set of natural numbers are bounded, but these are not in the real number system.
Big O gives an upper bound whereas big theta gives both an upper bound and a lower bound.
