Transcript of Honors Precalculus Summer Assignment - Fall River Precalculus Summer Packet...Honors Precalculus...

• Honors Precalculus Summer Assignment

Welcome to Honors Precalculus! This summer review assignment is designed to refresh your Algebra 2

skills. It includes information that was taught in Honors Algebra 2 and will be used throughout the

Precalculus course.

Assignment Requirements: You MUST show all work in order to receive credit! This includes the

multiple choice problems. All work must be done on a separate sheet of paper in a neat and organized

manner. No work, no credit! Please fill in the correct multiple choice answers on the provided bubble

sheet. The majority of the questions should be completed without the use of a calculator.

Due Date: This packet must be completed by the first day of school. Ten points will be deducted for each

day that the packet is late.

Grading: This assignment will be collected and graded upon completion and correctness. It will count as

an assessment grade for Term I. During the first week of school, a test on this material will be given during

class.

About Honors Precalculus: Honors Precalculus is a rigorous and fast-paced course. This standards based

course that meets every other day emphasizes the use and application of polynomial, rational, radical,

logarithmic and trigonometric functions and their application and the concept of theory of limits. There will

be extensive use of the graphing calculator, which is required for this course.

Questions?: If you have any questions about the Precalculus course or if you are having difficulty with this

packet, there will be help available in the IMC on Wednesdays from 10:00 am to noon (starting July 6th).
