Question

Intervalele sunt [-2, 3) (-4, 1] calculati A reunit cu B , A intersectat cu B , A minus B , B minus A

Answer 1

[-2,3)={-2,-1,0,1,2}=A
(-4,1]={-3,-2,-1,0,1}=B
A∪B={-3,-2,-1,0,1,2}
A∩B={-2,-1,0,1}
A-B={2}
B-A={-3}

Answer 2

[-2;3)
(-4;1]
AUB=(-4; 3)
A intersectat B= [-2; 1]
A-B= (-4; -3)
B-A=(1;3)
