Practice Exam for the final exam.
Solutions to the final practice exam.

Homework 10 is due on Friday December 6, 2013:
Section 11.5: 2, 12, 28, 42, 46.
Section 11.6: 2, 8, 12.
Section 11.7: 2, 6, 14, 24, 32.
I also suggest practicing with more exercises. Doing the odd exercises near the assigned exercises and others that look similar.

Practice Exam for the third midterm.
The solutions to the practice exam can be found here.

Here is a link giving a better explanation of compound interest which was discussed in class.

Second practice exam and its Solutions.

Solutions to Homework 7.

The word problem worksheet is here, and its solutions are here. Note that the answer for part d in exercise 1 should be 2010 instead of 2011 (since the overtake happens during 2010 around November). Also note that I didn't include the solution to the fifth exercise because it's example 3 of section 3.5 (page 178).

On the following Link you can find the actual graphs of the examples we did in class. you can see they have the same shape. (Note: I omitted the (x^2+4) terms from examples 2,3,4).

Midterm 1
