The second exam covers Chapter 2 (including Sections 2.1 and 2.2) and Section 3.1. It is recommended that you go over homework problems (HW# 4 - 6), your class notes and the quizzes. Many of the problems and questions we discuss in class are excellent examples of test questions. The solutions to your WebAssign problems on HW# 4 - 6 can be seen by clicking "View Key" near the top of each assignment. A WebAssign review "assignment" (not to be turned in) including many of the same homework problems (but with different numbers) will be available for practice purposes on Oct. 22nd at 5pm.

I have also listed some sample problems from the Chapter 2 Review Exercises below. The odd answers are in the back of the book while the evens are listed here. The Concept-Check at the end of each chapter (before the exercises) is also a source for good questions. The exam will be designed to take roughly one hour although you will have the full class period (plus a little extra) if necessary.

**Exam Review Session:** Monday, Oct. 26th, 8:00 - 9:30 pm in O'Neil 112.

Please come prepared with specific questions.

** Note:** You will be given a scientific calculator for the exam which does NOT have graphing
capabilities so be prepared to answer questions without your personal calculator.

**Chapter 2 Review Exercises, pp. 165 - 168**

Problems: 1, 3, 4, 5, 7, 9, 13, 14, 16, 18, 21, 23, 25,
27, 29, 30 (a and b), 33, 34, 35, 36, 37a, 39, 40, 41, 42, 45

The answers to the evens are:

4. 0

14. 1/3

16. 0

18. -1

30. (a) f'(2) = 10, (b) y = 10x - 16

34. Your graph should be positive (above the x-axis) until a
small positive x-value, then become negative (below the x-axis).

36. Your graph should be discontinuous at the cusp since the function
is not differentiable at that point.

40. a = f, b = f'' and c = f'.

42. This is just like Nixon's statement on inflation. The
first derivative of the cost of living function is positive since the
cost rises but the second derivative is negative because it is rising
at a slower rate (slopes decreasing means concave down).
