Finbar invested money in a transportation stock whose growth is modeled by the function f(x) = 0.01(2)x, where x represents number of days. find the approximate average rate of change from day 11 to day 15.
a.0.013
b.4
c.76.8
d.307.2

C.76.8

Step-by-step explanation:

We know that the average rate of change of any function f(x) from x=a to x= b is given by :-

Given : Finbar invested money in a transportation stock whose growth is modeled by the function , where x represents number of days.

Then , the  average rate of change of any function f(x) from day 11 to day 15 is given by :-

Hence, the approximate average rate of change from day 11 to day 15 = 76.8

Thus , the correct answer is option C. 76.8
