Question

Represente na forma tabular:

A = {x ∈ Z | - 3 ≤ x ≤ 3}

B = {x ∈ Z | x² = 9}

C = {x ∈ N | x² = 9}

D = {x ∈ N | 9 ≤ x  54}

Andre Smaira · Answer

A forma tabular equivale a demonstrar todos os valores que comportam o conjunto.

---

Iremos desenvolver cada um dos conjuntos em sua forma tabular individualmente, sendo elas a representação de todos os valores que satisfazem a desigualdade.

---

A= {x ∈ Z | - 3 ≤ x ≤ 3} na forma tabular: {-3,-2,-1,0,1,2,3}.

---

B={x ∈ Z | x² = 9} na forma tabular: {-3,3}.

---

C= {x ∈ N | x² = 9} na forma tabular: {-3,3}.

---

D= {x ∈ N | 9 ≤ x 54} na forma tabular: {9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54}.

Portanto, na forma tabular temos $\boxed{A = {\text{ }}\left\{ { - 3, - 2, - 1,0,1,2,3} \right\}}$ , $\boxed{B = {\text{ }}\left\{ { - 3,3} \right\}}$ , $\boxed{C = {\text{ }}\left\{ { - 3,3} \right\}}$ , $\boxed{D = \left\{ {9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54} \right\}}$ .
