Q: State whether the following statements are true or false: 1. Let S be a non-empty subset of the set of real numbers R. Ir s is bounded above, then Sups is exist, but need not to be unique in general. 2. If A = (-5,5) and B = (5,10), then Inf(A + B) = 10 and Sup(A + B) = 15. 3. The closed interval [1,2] has no maximal element. 4. The set of natural numbers N of R is unbounded. 5. The set of real numbers R, has Sup(R) = o and Inf(R) = -co. 6 The set S= (x E RỊ x? - 25 s 0} has Max(S) = 5 and Inf(S) = -5 with no minimal %3D element. 7. The set S = {1+nez*} has Max(S) = 2 and Min(S) = 1. 8. Every bounded set of real numbers R has maximal and minimal elements. 9. The properties (M2) and (M2) of the definition of the metric space are state that the distance from any point to another is never negative, and that the distance from a point to itself is zero. 10. There are many metric functions d: M x M -R that can be defined on a non-empty set M.
Determine if these functions are reflexive, symmetric, antisymmetric, and/or transitive. a. {(x, y) | x = ëyû} on the set of real numbersb. {(m, n) | m2 = n2 } on the set of integersc. {(a, b) | classroom a has a larger capacity than classroom b} on the set of classroomsd. {(1, 1), (2, 2), (1, 2), (2, 3), (3, 2), (3, 3)} on the set {1, 2, 3}
Let X {n ∈ N : 0 ≤ n ≤ 999} be the set of all numbers with three or fewer digits. Define the function f : X → N by f (abc) a + b + c, where a, b, and c are the digits of the number in X (write numbers less than 100 with leading 0’s to make them three digits). For example, f (253) 2 + 5 + 3 10. (a) Let A {n ∈ X : 113 ≤ n ≤ 122}. Find f (A). (b) Find f −1 ({1, 2}) (c) Find f −1 (3). (d) Find f −1 (28). (e) Is f injective? Explain. (f) Is f surjective? Explain.
Suppose f: R → R is a function from the set of real numbers to the same set with f(x) = x + 1. We write £ to represent fo f and fatl= fof. Is it true that £22o f = fo f?? Why? Is the set {g: R R | gof=fog} infinite? Why?
Consider the set M = {0, 2, 4, 6} and N = {1, 3, 5, 7}. Determine if each of the following ordered pairs is a function with domain M and codomain N. If you state it is a function, then determine if it is one-to-one and/or onto. a. {(0,2), (2,4), (4,6), (6,0)} b. {(6,3), (2,1), (0,3), (4,5)} c. {(2,3), (4,7), (0,1), (6,5)} d. {(2,1), (4,5), (6,3)} e. {(6,1), (0,3), (4,1), (0,7), (2,5)}
Help me please
13. (9 points) Let D be the set of finite subsets of positive integers. Let S be the set of all positive integers greate than or equal to 2. Define a function T:S → D as follows: For each integer n ≥ 2, T(n) = the set of all even factors of n. a) Find T(10). b) Find T(17) c) Find T(m), where m is any odd positive integer.
