Question

Considerando o conjunto universo U = {- 2, - 1, 0, 1, 2, 3, 4, 5} e dados A = {x U | x ≤ 3}, B = {x U | x é ímpar} e C = {x U | - 2 ≤ x < 1}, determine: a) A – C b) C – B c) (A C) – B d) C (A – B)

Answer 1

A={-2,-1,0,1,2,3}
B={-1,1,3,5}
C={-2,-1,0,1}

a) A-C = {2,3}
b) C-B = {-2,0,1,3,5}
c) AC-B  = {-1,1,2,5}
d)?
