a) Define a relation R on R (the set of all real numbers) as follows: For all x, y E R, xRy → x < y. Is R reflexive, symmetric and transitive?

The domain for the relation R is the set of all integers. For any two integers, x and y, xRy if x evenly divides y. An integer x evenly divides y if there is another integer n such that y = xn. (Note that the domain is the set of all integers, not just positive integers.) Symmetric Transitive Anti-symmetric Reflexive
Implement the following Racket functions: Reflexive-Closure Input: a list of pairs, L and a list S. Interpreting L as a binary relation over the set S, Reflexive-Closure should return the reflexive closure of L. In mathematics, the reflexive closure of a binary relation R on a set X is the smallest reflexive relation on X that contains R. (https://en.wikipedia.org/wiki/Reflexive_closure) Examples: (Reflexive-Closure '((a a) (b b) (c c)) '(a b c)) ---> '((a a) (b b) (c c)) (Reflexive-Closure '((a a) (b b)) '(a b c)) ---> '((a a) (b b) (c c)) (Reflexive-Closure '((a a) (a b) (b b) (b c)) '(a b c)) ---> ((a a) (a b) (b b) (b c) (c c)) (Reflexive? '() '(a b c)) ---> '((a a) (b b) (c c)) You must use recursion, and not iteration. You may not use side-effects (e.g. set!).

Consider f : X →Y, with domain X = {c, j, v, m, e, s, n, q, u, d, i, g} and codomain Y = {80,08, 57, 97, 82, 74, 39, 84, 01, 35, 15, 94}, as defined below using the set of expressions of the form f(a) = b. It is currently a bijection. Which of the following sequences of operations would cause this function to lose its surjectivity while still remaining a valid injection? f(e) f(g) f(j) f(s) f(v) f(m) f(c) f (u) f(d) f(n) = 39 f(q) f(i) = 82 = 94 = 08 = 74 57 = 97 = 80 = 01 = 35 84 = 15 Select one: O add 10 to the codomain → remove 80 from the codomain – change the preimage of 94 to d O add k to the domain → change the preimage of 84 to m → remove 35 from the codomain O remove 74 from the codomain → remove g from the domain → change the preimage of 15 to d O change the preimage of 01 to d → change the image of j to 82 → change the preimage of 08 to j O none of these options O add 37 to the codomain – change the image of d to 37 → remove n from the domain O remove d from the domain…
