1 Math 131, Final Exam Review-copyright Angela Allen 1 Math 131 Final Exam Review Sheet *** Important Reminders *** Remaining office hours: Mon.(4/28) 2-3:30pm, Thurs.(5/1) 1:30-3pm, and Fri.(5/2) 10:30am- 12pm. Remember, I cannot respond to s after Sun.(5/4), so be sure you get your questions answered before then. Bring a blank, green scantron to the exam (and a pencil!) When you are told to do so, you will fill in your name, section #, exam version, and regular class seat # on your scantron. Bring your picture i.d. Bring your calculator. (You will clear your calculator before the exam starts as usual, and remove your lid from the calculator. Also, make sure your batteries are charged.) Make sure you are in the correct seat (the exams will be labeled with your name so it is important that you are in the correct seat so we can start on time); the seating chart will be posted at the back of the room. You may NOT have scratch paper; there is plenty of room on the exam itself to work the problems. When you come into the room, place your bags against the wall and make sure your cell phones are turned OFF. You may NOT leave the classroom under any circumstances during the exam. When you turn in your exam, place your scantron INSIDE your exam. Your final exam grade and course letter grade will be posted on WebCT (elearning) by Friday evening, May 9. **********The last day you can get your grades (including your final exam grade) from WebCT is Wednesday, May 14. If you do not get your final exam grade from WebCT by this date, you will have to wait until next semester to stop by my office hours to get your final exam grade.***************** I cannot give extra credit under ANY circumstances. I cannot discuss grades via or phone. If you have a question about your final exam grade or course grade, you will have to me at the beginning of next semester to set up an appointment to meet. Chapter 1 ( ) Rules for combining functions (inputs same?, etc.) Combine functions Use intersect on your calculator to solve equations Know the elements of a model Linear Model: 1. f(x) = ax+b 2.
