Build the perfect disjunctive form and the perfect conjunctive form for each function. Assume that on all sets where the function is not equal to 0, it is equal to 1. Minimize each function by the Karnaugh method and the Quine method. 1. fix, X2, X3, Xa) = 0 on the sets 0, 1, 3, 5, 6, 7, 10, 11. 2. f\X1, X2, X3, Xa) = 0 on the sets 5, 6, 8, 10, 11, 12, 14, 15. 3. f(x1, x2, X1, Xa) = 0 on the sets 0, 2, 3, 7, 11, 13, 14, 15. 4. flx1, x2, X, Xa) = 0 on the sets 1,4,7,8,9, 11, 12, 15. 5. f(x1, X2, X, Xa) = 0 on the sets 1, 2, 3, 4, 12, 13, 14, 15
