It looks like you want us to do your homework for you. That will not help you understand what's going on in class.
Questions like #3, #4, and #9 are very basic. If you can't do those, that says to me you don't understand what's going on.
See your instructor, a classmate, or a tutor. Have them sit down w/ you one-on-one and explain the basic concepts to you. You'll find that once you understand these concepts, the answers will start rolling in like a flood. This is a much better investment of your time at this point. Good luck

if you have a graphing calculator, they are easy to find.
I can't solve them off the top of my head.
