Question

sa se determine elementele multimii: A={x€ Z | -3 < x mai mic este egal cu 5}

Answer 1

$A=\left\{x \: \in \: \mathbb{Z} \: | \: - 3 < x \leqslant 5 \right\}$

$- 3 < x \leqslant 5 = ( - 3,5]$

$x \: \in \: \mathbb{Z} = > x \: \in \: \left\{-2,-1,0,1,2,3,4,5\right\}$

$= > A=\left\{-2,-1,0,1,2,3,4,5\right\}$
