Question

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

Answer 1

Answer:

Yes

Step-by-step 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.

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