Question

Descreve os conjuntos mostrados, enumerando seus elementos: a) F = {x  IN / x ≤ 9}
b) G = {x  Z / x > 2, x é impar} c) H = {x  IN / x > 3, x é par} d) I = {x  IN / x > 1}
e) J = {x  IN / 3 < x < 8} f)A={x IN/x≤5} g)B={x IN/2< x≤7}
h) C = { x  Z / -2 ≤ x < 0}
i) D = { x  IN / x2 + 4x – 12 = 0} j) E = {x  IR / 5x2 + x = 0}
l) F = { x  Q/ -3x2 + 6x = 0} m)G={x IN/4< x < 8} n) H = {x  Z* /-3 ≤ x ≤ 1}
