Explicação passo-a-passo:
a) A=(-11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4) B=(0,1,2,3,4,5,6,7,8)
A∪B=(-11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8)
A∩B=(0,1,2,3,4)
b) A=(-7,-6,-5,-4,-3,-2) B=( -∞,-7,-6,-5) ∞ = infinito
A∪B=( -∞,-7,-6,-5,-4,-3,-2)
A∩B=(-7,-6,-5)
c)A=(-3,-2,-1,0,1,2,3,4,5) B=(-1,0,1)
A∪B=(-3,-2,-1,0,1,2,3,4,5)
A∩B=(-1,0,1)
d) A=(-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5) B=(1,2,3,4,5,6)
A∪B=(-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6)
A∩B=(1,2,3,4,5)
e)A=(-14,-13,-12,-11-10,-9,-8,-7,-6,-5,-4,-3,-2) B=(,-1,0,1,2)
A∪B=(-14,-13,-12,-11-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2)
A∩B=( ∅ )
