Question

Let D = {-2 -1. 0. 1. 2}. Is D a subset of itself? Explain.

Answer 1

Yes

Explanation:

Given

`D = \{-2,-1,0,1,2\}`

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.

`D = \{-2,-1,0,1,2\}`
