Answer:
Yes
Step-by-step explanation:
Given
[tex]D = \{-2,-1,0,1,2\}[/tex]
Required
Is D a subset of itself?
A subset is defined in such a way that, all elements of the subset can be found in the main set.
So; because set D contains all of its elements, then D is a subset of itself.
[tex]D = \{-2,-1,0,1,2\}[/tex]
