Question

São dados os conjuntos:
A={X € Z| - 4<X ≤ 2}
B={X € IN| X ≤ 3}
C={X € Z | -2<X<5}
D={X € Z | 3≤ X ≤8}

Determine

a) AUB
b) A∩B
c) AUB
d) A∩D
e) AUBUD
f ) AUB∩C
g) A∩B∩C∩D
h) (AUD) ∩ (BUC)
g) (A∩D) U (B∩C)
​

Answer 1

Explicação passo-a-passo:

primeiro vamos descobrir os valores incluindo nos conjuntos.

A= {-3, -2,-1,0,1,2,3}

B= {0,1,2,3}

C= {-1,0,1,2,3,4}

D= {3,4,5,6,7,8}

agora as questões

a) {-3,-2,-1,0,1,2,3}

b) {0,1,2,3}

c) {-3,-2,-1,0,1,2,3}

d) { nulo}

e) {-3,-2,-1,0,1,2,3,4,5,6,7,8}

f) {-1,0,1,2,3}

g) {3}

h) {-1,0,1,2,3,4}

i) {1,2,3}
