These and similar questions have been recently answered, so you would learn more from studying the solutions given and so gain the understanding to tackle the problems yourself. You will get more of a kick from being able to solve them yourself than just having someone else work out the answers for you. When you do understand the methods you will have successfully prepared yourself for the concepts of calculus. If you are having difficulties understanding then leave a comment against the solutions and I or someone else will try to help you understand.

Best wishes
