Answer:
[tex]\{\alpha \in \mathbb{Z} : \alpha > 4 ,\alpha \leq -1\}[/tex]
Step-by-step explanation:
Allowed values for the first set.
[tex]\{x \in \mathbb{Z} : x \leq -1\}[/tex]
-1, -2 -3, -4....
Allowed values for the second set.
[tex]\{ n \in \mathbb{Z} : n > 4\}[/tex]
5, 6, 7, 8....
Our final set is the union of
[tex]\{-1,-2,-3,-4...\}\cup \{5, 6, 7, 8...\}[/tex]
We can represent this as
[tex]\{\alpha \in \mathbb{Z} : \alpha > 4 ,\alpha \leq -1\}[/tex]
