Question

Enumero os elementos dos conjuntos:

 

a) x= {x        | -10<x<10}

 

b) y= { y     | -10< y <10}

Answer 1

Supondo x ∈ Z

a) x= {x        | -10<x<10} 

X = {-9,-8,-7,-6,-5,-4,-3,-2,-1,0, 1, 2, 3, 4, 5, 6, 7, 8 ,9}

b) y= { y     | -10< y <10}

Y = {-9,-8,-7,-6,-5,-4,-3,-2,-1,0, 1, 2, 3, 4, 5, 6, 7, 8 ,9}
