Precalc Review Key

A couple of things here. First, I need to get you more practice with the complex zeros...I don't like the problems I gave you. We'll do that tomorrow. Secondly, there are typos on #23 and 27. #23 should read -4x, and #27 should read +16. Sorry about that. I forgot to graph some of the complex numbers too.

This is first time I've given this packet.

All this said, here is the key.
