Question

1) Dados os conjuntos A = {0, 1,-1}, B = (-2,3) e C = {4}, represente mediante pares ordenados os produtos:

a) AxB b) Bx A

c) B? d) Cx B

e) Ax C ) Bx C​

Answer 1

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

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

C) B²= B X B = {(-2,-2),(-2,3),(3,-2),(-3,-3)}

D) C X B = {(4,-2),(4,3)}

E) A X C = {(0,4),(1,4),(-1,4)}

F) B X C = {(-2,4),(3,4)}
