Let X be a set and let R be the relation "" defined on subsets of X.

Prove whether reflexive, symmetric, transitive.

Is this the right approach?

Proof: (Reflexive)

Suppose S is a subset of X. Suppose y is in S.

(Now I need to show that (y, y) is in R. Can I say that y y, so (y, y) is in R?

I don't understand how to show thatelementsare in this relation since the relation is in terms of subsets.)
