ME AJUDE POR FAVOR

Determine A ⋂ B e A U B, sendo: a) A = {x ∈ ℕ | x ≥ 4} e B = {x ∈ ℕ | x < 7} *
( ) A ⋂ B= {5,6} e A U B ={0,1,2,3,4,5 ...= ℕ}
( ) A ⋂ B= {4,5,6} e A U B ={0,1,2,3,4,5,6,7,8... = ℕ}
( ) A ⋂ B= {4,5,} e A U B ={0,1,2,3,4,...= ℕ}
( ) A ⋂ B= {0,1,2} e A U B ={0,1,2,3,4,5,6,7}
( ) A ⋂ B= { } e A U B ={0,1,2,3,4,5...= ℕ}​

Answer 1

Resposta:

A U B = {0,1,2,3,4,5,6,7,8,9...} e A ∩ B = {5,6}.
