Honors Pre-Calculus Summer Assignment

2017-18 School Year

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 on 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 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?: Starting July 13th

Ms. Mullen will be in the IMC on Thursdays from 10am to noon if you need

extra help. If you have further questions, also try emailing your teacher or math department dean.
