71.       Let A and B be two fuzzy integers defined as:
A={(1,0.3), (2,0.6), (3,1), (4,0.7), (5,0.2)}
B={(10,0.5), (11,1), (12,0.5)}
Using fuzzy arithmetic operation given by
(A) {(11,0.8), (13,1), (15,1)}
(B) {(11,0.3), (12,0.5), (13,1), (14,1), (15,1), (16,0.5), (17,0.2)}
(C) {(11,0.3), (12,0.5), (13,0.6), (14,1), (15,1), (16,0.5), (17,0.2)}
(D) {(11,0.3), (12,0.5), (13,0.6), (14,1), (15,0.7), (16,0.5), (17,0.2)}

72.       Suppose the function y and a fuzzy integer number around -4 for x are given as
y=(x-3)2+2
Around -4={(2,0.3), (3,0.6), (4,1), (5,0.6), (6,0.3)} respectively. Then f(Around -4) is given by:
(A) {(2,0.6), (3,0.3), (6,1), (11,0.3)}
(B) {(2,0.6), (3,1), (6,1), (11,0.3)}
(C) {(2,0.6), (3,1), (6,0.6), (11,0.3)}
(D) {(2,0.6), (3,0.3), (6,0.6), (11,0.3)}
