m The domain for relation R is the set of all real numbers. fly it x - y is rational. A real number r is rational if there are two integers aand b. such that b a: D and r = alb. You can use the fact that the sum of two rational numbers is also rational. (a) The domain for the relation is ZxZ. (a, b) is related to (c. d) if a s c and b 1: d. Eh) The domain for the relation is 2x2. (a, b) is related to (c. d) if a <_: c or b <_: d (inclusive or). (i) The domain for relation T is the set of real numbers. XTY if x + y = D. (i) The domain for relation 2 is the set of real numbers. ny if y = 2):. (k) The domain for relation T is a group of people. xTy if person 3! is taller than person x. There are at least two people in the groupwho are not the same height. (I) The domain for relation C is a group of people. ny if person x is the first cousin of person y (is, a parent of person 2:: is a sibling ofa parent of person y). You can assume that there at least two people 1: and y such that x is the first cousin of y. You can alsoassume that no one has two parents who are siblings of each other.
