DON'T Freak Out!!!! This homework was a "wake-up" call that you need to do these and be careful with the presentations of proofs. It is not important what you get on this...or the example exercises. Just make sure you know how to do them when a test comes around.
Note - same authors of different books so page numbers in these notes may not match page numbers in the 650 book. General graph stuff in our text is page 112-124.
