Question

Jika K={ x | -5 ≤ x ≤ 4 , x bilangan bulat}
L={ x | -1 ≤ x ≤ 6 , x bilangan asli}
maka K υ L ?

Answer 1

K = {-4,-3,-2,-1,0,1,2,3,4}
L = {-1,0,1,2,3,4,5,6}
K U L = {-4,-3,-2,-1,0,1,2,3,4,5,6} atau bila ditulis dalam interval adalah -4 ≤ x ≤ 6 dgn x bil bulat

Answer 2

K= {-5,-4,-3,-2,-1,0,1,2,3,4}
L= {1,2,3,4,5,6}

K U L = {-5,-4,-3,-2,-1,0,1,2,3,4,5,6}
