Question

{XES/ -5 < X < 5}
{XES/ -3 < X ≤ 0}
{XES/ -1 < X < 3}
{XES/ 4 ≤ X ≤ 4}
{XES/ X > -2}
{XES/ X ≤ +2}

ME AJUDAAAAA

Answer 1

XES vou entender que seja aos inteiros.

{XES/ -5 < X < 5} = {-4,-3,-2,-1,0,1,2,3,4}

{XES/ -3 < X ≤ 0} = { -2,-1}

{XES/ -1 < X < 3} = {0,1,2}

{XES/ 4 ≤ X ≤ 4} = { 4 }

{XES/ X > -2} = { -1,0,1,2,3..,∞}

{XES/ X ≤ +2} = { 1,0,-1,-2,-3..}
