Question

A={-1,0,1} B={1,2,3} A reunit cu B; A intersectat cu B; A minus B; B minus A; A ori B; B ori A (reunit intru un plan) URGENT DAU COROANĂ​

Answer 1

Răspuns:

A reunit cu B ={ 0, -1 ,1,2,3}

A intersectat cu B ={1}

A minus B={ 0, -1}

B minus A={ 2,3 }

A ori B= { (-1,1) ,(-1,2) ,(-1,3) ,(0,1) ,(0,2),(0,3),(1,1),(1,2),(1,3) }

B ori A={(1,-1),(1,0),(1,1),(2,-1),(2,0),(2,1),(3,-1),(3,0),(3,1)}
