Question

Represente cada conjunto na forma tabular.
 a)A={x ∈ z l $x^{2}$ = 9}
 b)B={x ∈ z l $x^{2}$ ≥ 0}
c) C={x ∈ z l $\frac{1}{x}$ = 0}
d) D={x ∈ z l 56 < x ≤ 118}

Answer 1

 a)A={x ∈ z l  = 9} 
S = {-3,+3}
b)B={x ∈ z l  ≥ 0}
S = {0,1,4,9,16,25 ...}
c) C={x ∈ z l  = 0}
S = {0}
d) D={x ∈ z l 56 < x ≤ 118}
S = {57,58,59,60,61 ... 113,114,115,116,117}
