Answer 1

Respuesta:

Explicación paso a paso:

1) A = ]-3, 5[

B = ]-6, ∞+ [

C = ]-5, 2]

a) A ∪ B = ]-6, ∞ + [

b) A ∩ B = ]-3, 5[

c) A - C = [3, 4]

d) A ∪ C = ]-5, 5[

e) B - C = {x = -5, x ≥ 3}

f) A ∩ B ∩ C = ]-3, 2]

2) A = [-2, 4]

B = ]0, ∞ + [

C = [-5, 2[

a) A ∩ B = ]0, 4]

b) B - C = [2, ∞ + [

c) A ∩ B ∩ C = [1, 2[

d) A ∪ C = [-5, 4]

e) (A ∪ B) - C = [2, ∞ + [
