Answer:
Step-by-step explanation:
Given that Z the set of integers is the universal set and
A is given in set builder form.

To convert this into roster form, we can find solutions for x
When 
i.e. all integers lying between -2.236 and 2.236
The only integers satisfying this conditions are
-2,-1,0,1,2
Hence A in roster form is
A=
I think the answer would be 1.8
