1 Welcome to Accelerated PreCalculus! I look forward to getting to know you and working with you during the school year. While you are enjoying your summer, please take time out to complete the attached assignments. This packet is designed to help make the transition into this challenging course as smooth as possible (and to keep your math skills from deteriorating from lack of use). One thing is for sure the more you do over the summer, the easier it will be when school starts and the more comfortable you will feel with the pace of the class. Your summer assignment consists of problems that cover the following concepts: Part : Prerequisite Skills Eponent Rules, The Quadratic Formula, Factoring and Polynomials Part : Domain, Range, Functions and Inverses Part : Logarithms Part : Triangles Part : Conic Sections You should recognize these concepts from Algebra II and Geometry. It is very important that you complete the summer work. Packets WILL BE COLLECTED on the FIRST day of school. A completion grade will be assigned to all students. At that point, if you have not completed the majority of the assignment, you have to work that much harder to earn the grade that you desire. We will spend some time in class reviewing the prerequisite skills covered in this packet, but we will NOT complete problems from this packet, as they are your responsibility to complete over the summer. You will be tested on this material within the first week of school. We will be building on all of these concepts for the rest of the year. These foundational skills and practice are very important!! Notes related to each concept area are posted below. If you need help, please use the resources that I have posted for you and venture out and discover on your own. Answers are attached at the end of this packet so you can check your solutions as you work. This does not mean copy the answers to complete the assignment. No work no credit!!! If you have questions or concerns, you can reach me by at saffol@fultonschools.org I will respond, but please understand that I do not check my as frequently in the summer as I do during the school year. I will still do my best to answer your question as quickly as possible. Give me your best work while giving yourself the opportunity to get off to a great start! I look forward to meeting you in August! ~ Mrs. Saffo The solutions are located in the attachment!! Make sure you check your work as you go! Summer Assignment Notes
