4 Function is a special type of relation ordered pairs Cartesian product Set
5 (a,b) = (c,d) if and only if a=b and c =d a = d and b = c a = c and b = d a - b = c -d
6 The set of second elements of the ordered pairs forming a relation called a Domain Range Function Relation

19 The set of even prime numbers is (2,4,6,8,10} {2,4,6,8,10,12} {1,3,5,7,9} {2}
20 If A⊆ B, and B is a finite set, then n (a) &lt; n(B) n(B)&lt;(A) n(A)≤ n (B) n(A)≥ n(B)
21 If A = {2m/m3= 8 , m€ Z} then A =

 {1,8,27} {4} (2,4,6} {2,16,54}
22 If 0 = {1,3,5.......}, then n (0) = Infinite Even numbers odd integers 99
23 If B ={x/x€ Z ^ - 3 < x < 6}, then n (B) = 5 {-3,-2,-1,0,1,2,3,4,5,6} 8 9
24 If a = {2m/2m < 9 ,m€ p} , the (n A) = {2,3,4,5,6,7,8} {2,4,6,8............16} { 4, 6} {2,3,5,7}
25 If C={p/p < 18, p is a prime number}, then C = {2,3,4,.........17} {2,4,6,8................16} {1,3,5,7,9,11,13,15,17} {3,6,9,12,15}
26 If A = {x/x is a positive integer and 4≤x<23}, then A= {1,2,3,4,5,6,7} {4,5,6...........22} {1,2,3,.........23} {1,2,3,4,5}
