QUESTION #54 Types of Relations
Let A = -3, -2, -1, 0, 1, 2, 3 and R be a relation on A defined by xRy if and only if 2x - y in 0, 1. Let l be the number of elements in R. Let m and n be the minimum number of elements required to be added in R to make it reflexive and symmetric relations, respectively. Then l + mn is equal to:

QUESTION #58 Domain of Functions
Let the domains of the functions f (x) = _ 4 _ 3 _ 7 (8 - _ 2 (x ^ 2 + 4 x + 5)) and g (x) = ^ - 1 ((7 x + 1 0)/(x - 2)) be (α , β) and [ γ , δ ], respectively. Then α^ 2 + β^ 2 + γ^ 2 + δ^ 2 is equal to :-
