Question

Dados os intervalos: A = [-1, 6]; B = [0, 8) e C = (- ∞, 10]. Obtenha:
a) A ∪ B =
b) A ∩ B =
c) A ∩ C =
d) A – B =
e) B – A =
f) A – C =
g) C – A =
h) (A ∪ C) ∩ (B ∩ C) =

Answer 1

A= {-1,0,1,2,3,4,5,6}

B={0,1,2,3,4,5,6,7,8}

C={...-1,0,1,2,3,4,5,6,7,8,9,10}

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

b) {0,1,2,3,4,5,6}

c) {-1,0,1,2,3,4,5,6}

d) {-1}

e) {7,8}

f) {Ø}

g) {- ∞}

h) A U C {- ∞ -1,0,1,2,3,4,5,6,7,8,9,10}
B ∩ C {0,1,2,3,4,5,6} =
{0,1,2,3,4,5,6}



Espero que esteja certo
