I need some help with a college level pre-calculus homework. I will send you a screenshot of one question at a time and you will need to provide me an answer in next 20 minutes or so. You must have a skype account and be online (we will mutually setup the time frame). There are about 40 questions. Please bid only if you are a pro in calculus. The questions are really hard (for me at least) and could be advanced level.
