Question

Considere os conjuntos A = {-2,-1,0,1} e B = {0,1,2,3} e determine:

a) A U B
b) A N B

Answer 1

Resposta:

De se A ate B aumentou 2 em tudo entao precisamos calcular

A = {-2-1,0,1}

B = {0.1,2,3}

U = {19,20,21,22}

N = {12,13,14,15}

A) {-2-1,0,1}, {19,20,21,22}, {0.1,2,3}

B) {-2-1,0,1}, {12,13,14,15}, {0.1,2,3}
