Ethan's Finances

Five years ago, Ethan put some money in a savings account. The value of the

account in dollars as a function of t, the time in years the money has been in the

account, can be found using this function, as long as he makes no deposits to or

withdrawals from the account.

f (t) = 2000 (1.03)

Part A

What is the meaning of the number 2000 in this function?

Part B

At the same time that Ethan started his savings account, he bought a car. The value in dollars, of

the car as a function of t, the time in years since he bought the car, is shown in the graph.
