Honors Precalculus Prerequisite Packet
Updated 6/2015
Paint Branch High School Math Department
The problems in this packet are designed to help you review topics from previous math
courses that are important to your success in Honors Precalculus.
It is important that you take time during summer break to review the math concepts you learned this past school
year. In order to ensure that you are appropriately placed in, and prepared for Honors Precalculus, you may be
required to take a course pre-assessment when you return to school next year.
It is YOUR responsibility to prepare for the course pre-assessment!
The specific math concepts that will be assessed are listed on the front page of this summer packet. To prepare
for the course pre-assessment, you are encouraged to complete this summer math packet. Please note, this
summer math packet will not be collected or graded. Instead, the course pre-assessment will be used to measure
your knowledge of the prerequisite skills.
If you have any questions, please feel free to email the resource teacher, [email protected]
Concepts To Be Assessed
on the Honors Precalculus Course Pre-assessment.
Students should be able to:
 Simplify, add, subtract, multiply, divide and factor polynomial expressions.
 Solve quadratic equations.
 Simplify and evaluate rational expressions and complex fractions.
 Graph and identify properties of linear, quadratic, cubic, radical and rational functions.
 Apply rules of function notation, function composition and inverse functions.
 Solve a system of linear equations in two variables.
 Add, subtract, scalar multiply and find the determinant of matrices.
 Use the Pythagorean Theorem and trig ratios to find missing sides or angles of a right triangle.
 Use summation notation to express and determine the value of the sum of a sequence.
