Answer 1

a)
A = [-5;1) B = (-3;4)
A∪B = [-5;4)
A∩B = (-3;1)
A\B = [-5;-3]
B\A = [1;4)
b)
A = (-∞;1] B = [-1;8]
A∪B = (-∞;8]
A∩B = [-1;1]
A\B = (-∞;-1)
B\A = (1;8]
c)
A = [-4;6] B =  (1;6)
A∪B = [-4;6]
A∩B =  (1;6)
A\B = [-4;1]
B\A = ø
d)
A = [-1;7) B = [-1;2)
A∪B = [-1;7)
A∩B = [-1;2)
A\B = [2;7)
B\A = ø
e)
A = (-∞;2] B = [-1;1]
A∪B = (-∞;2]
A∩B = [-1;1]
A\B = (-∞;-1)
B\A = ø
