Question

dados os conjuntos a ={-2,-1,0,1,2} b = {-1,0,1,3} e C= {-3,-1,1,3,5} determine os conjuntos

a) A U B

B) A ∩ B

C) A U C

D) A ∩ C

E) B U C

F) B ∩ C

Answer 1

Resposta:

Explicação passo-a-passo:

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

B = {-1,0,1,3 }

C = {-3,-1,1,3,5 }

a)A ∪ B = {-2,-1,0,1,2,3 }

b)A ∩ B = {-1,0,1 }

c)A ∪ C = {-3,-2,,-1,0,1,2,3,5 }

d)A ∩ C = {-1,1 }

e)B ∪ C = {-3,-1,0,1,3,5}

f)B ∩ C ={-1,1,3 }
