I believe for the odd I got 0, and for the even I got an expression like 2^(n-1) * (1-n) or something like that, but I don't exactly remember.

What were your thoughts on the very last question (the one with the inequality)? 

I got 0 as well. I wasn't sure cuz it was kinda weird. What a relief. hahahahahah.

 

For the last one, it is hard to explain it here. I proved the inequality but I forgot I had my calculator and forgot to calculate the actual value.... Basically, when you know the complement and the orginal graph have the same edges, you can put them into a formula. (it is in hr formula booklet), and combine them, which gives you the equation.

I think one of my peers did something similar. It was the only question that truly stumped me. Overall, a great exam, though!
