73.       A fuzzy set A on R is ................. iff A(λx₁ + (1 – λ)x₂) ≥ min [A(x₁), A(x₂)] for all x₁, x₂ ∈ R and all λ ∈ [0, 1], where min denotes the minimum operator.

(A) Support

(B) α-cut

(C) Convex

(D) Concave

Answer: C

74.       If A and B are two fuzzy sets with membership functions

μ_A(x) = {0.6, 0.5, 0.1, 0.7, 0.8}

μ_B(x) = {0.9, 0.2, 0.6, 0.8, 0.5}

Then the value of μ_(A∪B)’(x) will be

(A) {0.9, 0.5, 0.6, 0.8, 0.8}

(B) {0.6, 0.2, 0.1, 0.7, 0.5}

(C) {0.1, 0.5, 0.4, 0.2, 0.2}

(D) {0.1, 0.5, 0.4, 0.2, 0.3}

Answer: C

Explanation:

μ_(A∪B)(x) = max{ μ_A(x), μ_B(x)}

μ_(A∪B)’(x) = 1- μ_(A∪B)(x)
