Question

Dados os conjuntos A = {x / – 5 ≤ x ≤ 8} e B = {x / – 1 < x ≤ 4}, então determine A – B.




Pffv preciso urgente!

Answer 1

Resposta:

Explicação passo-a-passo:

A = {x / – 5 ≤ x ≤ 8}         A=( -5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8)

B = {x / – 1 < x ≤ 4}          B=(0,1,2,3,4,)

A – B= ( -5,-4,-3,-2,-1,5,6,7,8)
