Question

Determine A ∩ B e A U B, sendo A = {x ∈ Z | x ˃ 1} e B = {x ∈ Z | x ≥ 3}​

Answer 1

Resposta:

A = 2,3,4,5 B = 1,2,3,4

a) A U B = 1,2,3,4,5, E A Intersecção B = 2,3,4

b) A = -1, -2, -3 B = -2, ,-1, 0, 1, 2

b) A U B = -3,-2,-1,0,1,2 A Intersecção B = -1,-2

c) A= -2,-1,0,1,2,3,4,5 B= 3,4,5,6,7,8

c) AUB= -2,-1,0,1,2,3,4,5,6,7,8 A Intersecção B = 3,4,5

Answer 2

Resposta:

A = 2,3,4,5 B = 1,2,3,4

b) A = -1, -2, -3 B = -2, ,-1, 0, 1, 2

 

c) A= -2,-1,0,1,2,3,4,5 B= 3,4,5,6,7,8
