7. $18,000 is deposited into a bank account that earns interest at a rate of 3.6% per year, compounded continuously. What is the formula that describes how much money is in this account as a function of time? How much money will be in the account in 8 years? At what rate (in dollars per year), will the money be growing in 8 years? 9. Calculate the area in between these two functions: f(x)=21x22x+6 and g(x)=21x2+4x6 from x=3 to x=6. (HINT: f(x) is always greater than g(x) over this interval.) Drawing a sketch of the graphs may help but it is not required
