Answer:
f(x) = 4(1.15)^(5x); growth rate is 15%
Step-by-step explanation:
If x still represents the number of years, but we want to see a growth factor that corresponds to 1/5 of a year, we can write the formula as ...
The growth factor is 1+r = 1.15, so r = 0.15 = 15%, the growth rate in a 1/5-year interval.

<em>Comment on the question and answer</em>
If Jan wants to compute the growth in 1/5-year intervals, it isn't clear why the desired formula uses an exponent of 5x, signifying that x is measured in years. We would expect the independent variable to be the number of 1/5-year intervals, rather than 1/5 that number.
