5. Compute the value of adding the following two fuzzy integers:

A = {(0.3,1), (0.6,2), (1,3), (0.7,4), (0.2,5)}

B = {(0.5,11), (1,12), (0.5,13)}

{(0.5,12), (0.6,13), (1,14), (1,15), (1,16), (1,17), (1,18)}

{(0.3,12), (0.5,13), (0.6,14), (1,15), (0.7,16), (0.5,17), (0.2,18)}

{(0.3,12), (0.5,13), (0.5,14), (1,15), (0.7,16), (0.5,17), (0.2,18)}

6. If the Fourier transform of the function f(x, y) is F(m, n), then the Fourier transform of the function f(2x, 2y) is :

1/4 F(m/2 , n/2)

1/4 F (2m, 2n)
