Web1. Another way to look at the second part comes from being a little more clear about notation. Your function f is a function, say, f: X → S. Now, for any such function, f − 1 ( S) ⊆ X. Furthermore, for any subset Y ⊆ X, we have that f ( Y) ⊆ f ( X) ⊆ S. Putting these two pieces together, we find that f ( f − 1 ( S)) ⊆ S as claimed.
