The exam will be all multiple choices. Know how to graph the functions and conics discussed above.
Review sheets or practice problems were given for some tests – these should be used to help you study
for your final. Also, several worksheets were given throughout the semester. You should review these.
Be sure to see me for correct answers for old tests, quizzes, and worksheets – I will have the binders
with answer keys available. This will make your studying time much more productive.
You may bring 1 – 3x5 index card for formulas, examples, etc.
