Answer:
[tex]\boxed{\boxed{\left\{x\ |\ x\ \epsilon\ Z,\ x \le 0}\right\}}}[/tex]
Step-by-step explanation:
Set builder notation-
It is a notation for representing a set by enumerating its elements and stating the properties that its members must satisfy.
The given set is,
[tex]\left \{.... -3, -2, -1, 0 \right \}[/tex]
This set is comprised of all negative integers. So symbol Z should be used in this case.
The set builder notation for this set is,
[tex]\left\{x\ |\ x\ \epsilon\ Z,\ x \le 0}\right\}[/tex]
