SUMMER STUDY PACKET
HONORSPRE-CALCULUS
DearHonors Pre-Calculusstudent,
This summerpacketis designedto help you practiceusingthe conceptsyou learnedin
HonorsAlgebra 2 (or Algebra 2) so that you arepreparedto study HonorsPre-Calculusthis fall.
The contentand philosophyof this summerpacketis oonsistentwith our departmentgoalsand
will enablethe studentto:
(l) valuemathematics,
(2) becomeconfident in their ability to do mathematics,
(3) become mathematicalproblem solvers,
(4) communicatemathematically,and
(5) to reasonmathematically.

The exerciseswere takenfrom the ChapterTestssectionofthe Algebra II textbook.You
how to do 4!! the exercisesnoted@Qgg the first day of classes.If
areresponsiblefor @i4g
you donot know how to do a problemyou are expectedto usethe sourcesavailableto you
(notes,handouts,books,Interne! etc.) to figure it out indeoendentlv.The beststudy routine
during the summermonthsis to constantlyreview topicsand do a few problemseachday, not
attemptyour
answers,Pleaserememberto showall ofyour work on the worksheets
provided.Work neatly and in an organizedway.
The problemsshouldbe done in chronologicalorder.Eachproblemshouldincludea
summaryofthe problem statement,a completestep-by-stepsolution,and a boxedfinal answer.
You shouldnot usea calculatorto do the problems,but you may useyour calculatorto check
your answer.
This summerpacketcontainsa review of the following:
a. exponents
b. roots
c. algebraicexPressions
d. multiplyingpolynomials
e. factoring
f. fractions
g. solving linear equationsand word problems
h. solving quadraticequations
i. complex numbers
j. linear functions
k. quadraticfunction
l. inversefunctions
m. polynomial functions:graphsand zeros
n. polynomialdivision
o. rationalfunctions
The summerassignment
will not be collectedbut you areexpectedto know how to solve
all the problems.Therewill be a brief reviewof thesetopicsduringthe first weekof classand
thenyou will be formallyevaluated
on your knowledgeof thesetopics.This testwill countas
l0% of your first quartergrade.The preparedAP Calculusstudentshouldeasilyscoreover 90%
on suchan exam.
