This assignment is a review of Pre-calculus and Algebraic concepts that you need to be familiar with in order to make a smooth transition into AP Calculus AB. It will be due when you return to school on August 6, 08 - NO EXCEPTIONS. I would suggest that you complete this during the last few weeks of summer so that it is fresh in your mind. A test over this material will be given on Thursday, August 9 th. I look forward to meeting you in class this fall and a great school year! I hope you have a great summer! - Coach Crawford For help on Precalculus concepts: http://www.khanacademy.org/ Scroll down on the home page to see many topics of interest. I. Analyzing Functions Use the figure at the right to answer the problems below:.
