Difficult: The difficult section for this reading was 9.2. I just don't think i really understood most of it. I didn't understand what it meant by B^(A) and why that notation was chosen or what it really meant.
Reflexive: I enjoyed section 9.1 for this reading which was on functions, domains, codomains, ranges, images, and mapping. I felt like all of these terms were based of fundamental concepts that I already understand. However I don't think that I understood why for f: A > B that A is the domain and B is the codomain.
