1. What is your math history (what classes have you taken and how recently.)  How did they go?

2. What are your goals for this class? (for example, to pass, to get an A, to prepare for calculus, to finish some requirement)

3.  What do you plan to do to reach those goals?  List at least 2 specific study habits you would like to meet. (For example: attend every class, form a study group for homework and quizzes.)

Remember to email to mccaffrc@pdx.edu by 11:00 pm Tuesday 6/22 and include Math 111 and your last name in the subject line.

Suppose that you turn on your oven and the temperature of your oven is increasing at a

linear rate. You forget to check the temperature of the oven when you turn it on. After

3 minutes the temperature is 136 degrees, and after 7 minutes the temperature is 224

degrees. EXPLAIN YOUR REASONING FOR EACH QUESTION.

a) Write an expression for the temperature of the oven as a function of time.

(BEWARE! The starting temperature of your oven is not 0 degrees!)

b) What is the y-intercept of this function? What does that mean in terms of this real

world situation?

c) What is the domain for this problem? What input values make sense in terms of

this real world situation?

d) How long does it take for the oven to reach 350 degrees (from the time that I

turn on the oven)? Explain how you found that value.

Due Tuesday 7/20 by 11:00 pm

The Raging Astronautics were a band that was slightly popular for a short period of time. The number of albums they sold each week is given by the function

(b) What week did the band sell the most albums?

(c) What was the maximum number of albums sold in that week?
