A bank account earns a fixed rate of interest compounded quarterly (every 3 months). Which statement is false.

• The value of the account increases at a constant rate over any unit time interval

• The value of the account increases at a constant percent rate per quarter

• The value of the account increases at a constant percent rate per year

• We could make an exponential function to model this situation.
