Answer 1

Resposta:

a) J={x e N / 3≤ x < 5} = {3,4}

b) H={x e N / 0 < x ≤ 5} = {1,2,3,4,5}

c) T={x e Z / -3 < x < 1} = {-2,-1,0}

d) D={x e Z / -5< x} = {-5,-4,-3,-2,-1,0,1,2,3,4,5,...}

e) E={x e N / 10 ≤ x< 15} = {10,11,12,13,14}

f) F={x e Z / -4 ≤ x < 2} = {-4,-3,-2,-1,0,1}

g) G={x e N / -3 < x ≤ 5} = {-2,-1,0,1,2,3,4,5}

h) I={x e Z / -15 < x < -10} = {-14,-13,-12,-11}

I) K={x e IN / 23 < x < 25} = {24}

j) J={x e N / 1 ≤ x <5} = {1,2,3,4}

k) H={x e N / 2 < x ≤ 5} = {3,4,5}

l) T={x e Z / 0 < x < 3} = (1,2}

m) D={x e Z / 3 < x} = {4,5,6,7,8,9,...}
