Anyway, posting 20 questions like this is not a good way to seek help on this forum. We don't do peoples homework for them !!! CH claim they have a tutorial system, so students of their courses should be asking for help there. The marks from each set of 20 questions are used to determine the student's progress and certificates awarded from these alone. So a student who 'cheats' by getting answers from someone can gain certification without any real understanding of the work. I do not wish to be a party to that sort of thing.
There's a simple way to get help here. Post a single question, explaining why 'you' cannot do it. Get help and try to solve it. Get more help if necessary. Then try the next one on your own and post your answer, asking someone to check it. If it's right, you've mastered the topic.
Thompsonnn: You've posted the work, but since made no comment. If I've made a mistake, please explain and we can get going with the help.

]]>It is a delicate issue: even though we obviously don't want to make enemies of these websites, it is not always easy to tell if a poster is breaching copyright by asking for help. Sometimes when someone posts one of these problems it has ended up launching some interesting mathematical discussions, and having to delete them because of a breach of copyright is a shame. Moreover, to what extent can a maths problem be 'copyrighted'?
]]>That's a lot of questions. Have you read the 'sticky'? http://www.mathisfunforum.com/viewtopic.php?id=14654
We have also had a complaint from Compuhigh about breaching their copyright in posts.
Unless you can confirm that this is not one of their homework sheets I shall have to delete it. Sorry.
I suggest you re-post asking for help about functions.
