A student makes a deposit into a savings account and makes no additional deposits or withdrawals. The value of the student's savings account can be modeled by the function f(z)2, 394(1.013)², where z is the time, in years, since the student's initial deposit.
If the function g (z)=2, 394(1+0.013)² is equivalent to f(z), and z≥ 0, which statement is true?
a. The function g (z) reveals the value of the savings account is decreasing by 1.3% each year.
b. The function g (z) reveals the value of the savings account is decreasing by 13% each year.
c. The function g (z) reveals the value of the savings account is increasing by 1.3% each year.
d. The function (z) reveals the value of the savings account is increasing by 13% each year.
