Cde: MATH 151 Title: INTERMEDIATE ALGEBRA Divisin: MATHEMATICS Department: MATHEMATICS Curse Descriptin: This curse prepares students fr curses that require algebraic skills beynd thse taught in Elementary Algebra. Tpics include equatins, inequalities, linear systems in tw and three variables, cmplex numbers, and applicatins f functins: linear, expnential, lgarithmic, quadratic, plynmial, ratinal, and radical. In additin, the curse prvides a basic intrductin t right triangle trignmetry. Prblems are apprached frm a variety f perspectives, including graphical, numerical, verbal, and algebraic. A graphing calculatr is required; the specific mdel is determined by the department.

COURSE LEARNING OUTCOMES: Upn cmpletin f this curse, students will be able t: Demnstrate the mathematical skills apprpriate t this curse. (M) Identify and characterize the fllwing functins: linear, expnential, lgarithmic, quadratic, ratinal, and radical by interpreting verbal, graphical, numerical, and symblic representatins. (M) Use the apprpriate functin mdel t analyze and slve applicatin prblems. (M) Interpret slutins in the cntext f the prblem. (M) Use a graphing calculatr t understand cncepts and t explre and slve prblems. (M) Learning Outcme(s) supprt the fllwing General Educatin Knwledge Areas: (M) Mathematics GRADING STANDARD: In this curse, yu will be evaluated by means f tests, quizzes, labs, and pssibly hmewrk. A. TESTS There will be fur tests, ne after each unit. Each test cnsists f tw parts: a nncalculatr part and a graphing calculatr part. Students may nt use any type f calculatr n the nn-calculatr parts f the fur tests. Tests will be cumulative. All supprting wrk must be shwn n tests in rder fr yur instructr t prperly assess yur understanding f the material. The tests will be given in class and it is expected that yu will be in class t take the test n the day it is given. If yu are very ill (verifiable with a dctr s nte) r yu have sme ther emergency, yu must cntact yur instructr immediately. B. LABS/QUIZZES/HOMEWORK There are labs in this curse t be cmpleted in class. They are dne in grups and may be assessed either individually r as a grup assignment. The activities cntain prblems that reinfrce the cncepts and skills learned in class. There are als peridic quizzes, and yur instructr may als chse t use hmewrk assignments fr evaluatin. GRADING Each test is graded n the basis f 100 pints. Yur final curse average is determined by a weighted average as fllws: Test 1 10% Test 2 20% Test 3 20% Test 4 25% Labs, Quizzes, Hmewrk 25% Page 2 f 7
FINAL GRADE Yur final grade is determined as fllws: If yur final curse average is Yur final grade is 90 100 A 88 89 A- 86 87 B+ 80 85 B 78 79 B- 76 77 C+ 70 75 C 60 69 D** Belw 60 F ** T use this curse as a prerequisite fr anther mathematics curse, yu must have a grade f C r better. Incmplete INC is nly given at the discretin f yur instructr. This may ccur in dcumented cases f hardship r emergency. In this case, yu must meet with the instructr t discuss the wrk that must be cmpleted t earn a grade in the curse. All wrk must be cmpleted within 21 days after the end f the term, exclusive f fficial cllege clsings. Withdrawal Yu may withdraw frm the curse, withut penalty, up t a date set by the Cllege. If yu d nt withdraw frm the curse but stp attending, yur grade at the end f the semester will be F.

1/14 DEPARTMENT POLICIES: The Math Department wants yu t be successful in this curse. Because f this, we have cmpiled a list f strategies and behavirs. Attendance and class participatin If yu want t be successful in this curse, attend every class. Cme t class n time, and stay fr the entire class perid. If yu are late r leave during class, yu will miss imprtant class material and yu will als distract yur classmates and yur instructr. (See the Student Cnduct Cde) Turn ff yur cell phne during class. Yu and yur classmates need t be free frm distractins. (See the Student Cnduct Cde) Bring yur bk and calculatr t every class. Respect yur classmates and yur instructr. Listen carefully t questins asked and answers given. Treat all questins with respect. Participate fully in class. Vlunteer answers, wrk prblems, take careful ntes, and engage in discussins abut the material. Abve all, stay n task. Cntribute yur share f wrk t yur in-class grup wrk and d yur best t make the grup experience a psitive ne fr all members. D yur wn wrk n tests and quizzes. Cheating will nt be tlerated. (See the Academic Integrity Cde.) Hmewrk Hmewrk is the way yu practice the ideas and skills that are intrduced in class. T be successful n the tests, yu must d the hmewrk. Hmewrk may be cllected and hmewrk questins may be included n quizzes r tests. All the hmewrk assignments are listed n the unit hmewrk assignment sheets. Hmewrk may be nline (see Required Materials) and may be graded. When yu d the hmewrk, write dwn all supprting wrk. Using the crrect prcess is at least as imprtant as getting the crrect answer, s yur wrk and steps are very imprtant. Remember t check yur answers. They will be in the back f the text r in the student s slutins manual. If there are questins yu can t get r dn t understand, ask abut them at the beginning f the next class. If yu have truble with mre than a few prblems, try starting yur hmewrk in the Math Lab, where help is available. Absence If yu are sick and an absence is unavidable, please call r email yur instructr. Yu are still respnsible fr all material that was cvered during yur absence. Yu are expected t read the textbk and d the hmewrk. Make time t see yur instructr when yu return s that yu can get any papers yu missed. Remember that yu are expected t be in class fr the tests and quizzes. Getting Help After yu have tried the hmewrk, if yu need help, there are several things yu can d: Lk in yur text and yur class ntes fr examples similar t the prblems yu are finding difficult. Page 6 f 7
1/14 See yur instructr during ffice hurs r make an appintment. Bring the wrk yu have dne. Frm a study grup with ther class members. Wrking with ther students can be a great way t learn. If yu d have a grup t wrk with, cnsider exchanging phne numbers r email addresses. Yur textbk may have a cmplete slutins manual available in the Math Lab. Yu may use this in the Math Lab. G t the Math Lab t get extra help n yur hmewrk r simply g and d yur hmewrk there. Smene will be there if yu get stuck. Yu dn t need an appintment.
