Section 24 due November 5

1. The logical step forward. I've noticed that we've spent most of our time with integers and natural numbers but I suspect that functions will have us working with real numbers in the future. I think I have a weak grasp on what is a "well-defined" function. Also, is it possible to have a function that is not well defined? or is it then not a function by definition? That was confusing.

2. I gotta be honest, it's nice to see functions again. Also, I'm anticipating this material to overlap a little more with our Linear Algebra class, which should be nice. I would like to have a better understanding of mapping and domains and codomains etc. (I'm not sure if we're really gonna get into that but we'll see) Also, it's nice to feel like we're focusing on a topic that I actually have quite a bit of experience with! I mean, most of my math career to this point has been related to functions.
