Resposta:

a) {x ε R / -3 < x ≤ 8} = {-2,-1,0,1,2,3,4,5,6,7,8}

b) {x ε R / -2 ≤ x < 6} = {-2,-1,0,1,2,3,4,5}

c) {x ε R / x < 7} = {..., -2,-1,0,1,2,3,4,5,6}

d) {x ε R / 5 ≤ x ≤ 10} = {-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9,10}

e) {x ε R / -2 < x ≤ 0} = {-1,0}

f) {x ε R / 0 ≤ x < 6} = {0,1,2,3,4,5}

g) {x ε R / x ≥ −5} = {-5,-4,-3,-2,-1,0,1,2...}

h) {x ε R / 15 < x < 19} = {16, 17, 18}

i) {x ε R / 13 ≤ x < 20} = {13, 14, 15, 16, 17, 18, 19}

Espero ter ajudado. Bons estudos.
