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.

Webs3 +1 s2 +1 = s+ −s+1 s2 +1. We, however, never have to do this polynomial long division, when Partial Fraction Decomposition is applied to problems from Chapter 6. Another important fact in Chapter 6 is that we use only the following three types of fractions: 1. s− a (s− a)2 +b2, 2. b Web1.
