## MAT123 Fall 2006 Review for Midterm II

**Note**: This exam will cover polynomial and rational functions as discussed in Sections 2.2 through 2.6, and exponential and logarithmic functions with various applications as discussed in Sections 3.1 through 3.5 of our text. The format of this test will be the same as for the first Midterm. Please bring your ID.

For this test you may use a graphing calculator, however, you must follow the instructions on our Course Description page as to which models are admissable. We will strictly enforce those rules. The calculators permitted may not be of use for all questions on the exam, notably when a problem asks for an exact answer. Make sure you have good batteries, you know how to set modes and appropriate window sizes, and you can plot and interpret simple graphs.
The topics for review can be found on pp367-374 and pp437-444 of the text.
