1 Attn: Upcoming Functions Analtic Geometr students, All Functions Analtic Geometr students should complete this assignment prior to the first da of class. During the first week of school, time will be spent answering questions students ma have on the material covered in this packet with the understanding that the will be assessed on these topics starting the second week of school and throughout the ear. This review will be in addition to covering new material from the first chapter, Functions and Their Graphs. Functions Analtic Geometr is a one-ear preparator course for AP Calculus BC. This course is designed for students who have successfull completed the standards for Pre AP Algebra II /Trigonometr. Throughout the ear students will learn various objectives which will challenge them and will help to enhance their problem solving skills. This packet was devised to help students be successful not onl in Functions Analtic Geometr but in all subsequent math courses as one of the goals of this class is to prepare students for the challenge of AP studies in mathematics. It is essential for students to master the skills covered in this packet. You must be able to understand and appl this information throughout the school ear. To best prepare for this class, it is recommended that students complete this packet within two to three weeks directl before school starts. Calculators should not be used to complete this packet. If some concepts are challenging and require a refresher of the material, two good sites for information are and If ou have questions regarding the nature of this course, the summer assignment or anthing else, please feel free to me. In the summer I usuall check m once a week. I will respond as soon as possible. Good luck! Enjo our summer vacation! I look forward to meeting ou in the fall! Ms. Modica modicalm@pwcs.edu
