### Notes:

• No calculators allowed on the in-class portion of the exam.
• None of the problems on the test are straight from the text, but should be similar to the problems in the text.
• There is none of 4.6 on the in-class test.
• There is a take-home portion of the exam worth 25 points and is due the class period after the in-class portion. This will be when we return from Spring Break, so you may wish to complete it before Spring Break so you don't have to worry about it over the break.
