The membership functions of Fuzzy set A and B on x are given below:

MuA (x) = piecewise function: 0 if x = 4

MuB (x) = piecewise function: 0 if x = 3

The membership fuctions of Fuzzy set A and B on * are given below O if 25 0 as if Osix O to * 1 - * / 2 if I s x x 2 0.5 x - 0.5 if Is 2 My ( * ) 1 + * / 2 if 2 5 x
