۲/ Determine all a-level sets and all strong a-level sets for the following fuzzy
sets:
a. A = {(3, 1), (4, .2), (5, .3), (6, .4), (7, .6), (8, .8), (10, 1), (12, .8),
(۱۴, .۶))
b. jj = {(x, llii(X) = (1 + (x - 10)2rl)}
for a = .3, .5, .8
c. C = {(x, Ile(x)) I x ER}
where Ilc(x) = 0 for x ::5 10
Ilc(x) = (1 + (x - 1Or2r 1 for x> 10
