Question

Sendo A = [ ,0 3 ] e B = [ ,1 5 ), determine:

a) A ∪ B

b) A ∩ B

c) A − B

d) B − A​

Answer 1

Resposta:

Explicação passo-a-passo:

A = [ ,0 3 ]  => A = {0,1,2,3}

B = [ ,1 5 ) => B {1,2,3,4,5,6,+ ∞}

a) A ∪ B => {0,1,2,3,4,5,6,+ ∞}

b) A ∩ B => {1,2,3}

c) A − B => {0}

d) B − A​ => {4,5,6,+ ∞}
