When an exponential function is given as
f(x)=ab^x, and
knowing that b^0=1, that means that
f(0)=ab^0=a value of function when x=0, or the initial value.
In the case of
f(x)=20.b^x, f(0)=20.b^0 = 20 (initial value)
If b=1.2, then the hourly growth rate is (1.2-1)=0.2=20%.
If b=1.85, then the hourly growth rate is (1.85-1)=0.85=85%.

Step-by-step explanation:
The coefficient, 0.25, of the expression represents the late fee for every day the book was overdue.
And the constant, 2, represents the fixed rental fee.
The variable, x, represents the number of days Joseph had the book for.
Hope this helps :)
