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?
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 that elements are in this relation since the relation is in terms of subsets.)
