2.   Each of the functions P, Q, and R in Section 3.4 Example 1 can be written in the form a(b)^t
      for some numbers a and b. If so, what would be the value of a? _______

3.   Each of the functions P, Q, and R in Section 3.4 Example 1 can be written in the form a(b)^t
      for some numbers a and b.
      Give the value of b for P =5e^0.3t (round to two decimal places)_________ 
      Give the value of b for Q =5e^0.2t (round to two decimal places)_________ 
      Give the value of b for R =5e^−0.2t (round to two decimal places)_________ 

4.   Suppose each of the functions P, Q, and R in Section 3.4 Example 1 represented populations of
      different countries (in millions), where t is given in years.
      For P =5e^0.3t the population grows at an annual rate of _____% per year
             and at a continuous rate of ____% per year.
      For Q =5e^0.2t the population grows at an annual rate of _____% per year
             and at a continuous rate of ____% per year.
      For R =5e^−0.2t the population decreases at an annual rate of _____% per year
             and at a continuous rate of ____% per year.

5. Suppose Account A pays 52% interest once per year. (OK, use your imagination.)
    Account B pays 1% interest every week. (Note there are 52 weeks in a year.)
    Without a calculator, decide which account is better after 1 year.
    o  Account A
    o  Account B
    o  Both the same.
