Question

Dados os conjuntos A e B, apresente o conjunto A ∩ B.
a) A = {x ∈ N∈ I 1 < x < 7} e B ={x ∈ N I x < 6}

b) A= {x ∈ Z I -3 < x < 3} e B= {x ∈ Z I -1 < x < 1}

c) A= {x ∈ Z I -4 < x < o} e B= {x ∈ N I -4 < x < 0}

d) A= {x ∈ Z I -3 ⊆ x < 3} e B= {x ∈ Z I -8 < x < -2}

Answer 1

a) A={2,3,4,5,6} / B={0,1,2,3,4,5}
A∩B={2,3,4,5}

b)A={-2,-1,0,1,2} / B={0}
A∩B={0}

c) A={-3,-2,-1} / B={-3,-2,-1}
A∩B={-3,-2,-1}

d) A∩B= {-3}
