Question

2) Qual é a união entre intervalos: A = [2,6] e B = [6,15].

a) {2, 3, 4, 5, 6}
b) {2, 3, 4, 5, 6, 7, 8, 9, 10 ,11 ,12,13, 14, 15}
c) { 6 }
d) { 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}

Answer 1

Letra B

A = [2, 3, 4, 5, 6]

B = [6, 7, 8, 9, 10, 11, 12, 13, 14, 15]

Fazemos a união!

AUB = [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
