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.

76.8

step-by-step explanation:

you are finding the slope of a line intersecting the given curve at x=11 and x=15.

that is you are computing:

so now we must compute f(15) and f(11).

f(15) means replace x in with 15.

f(11) means replace x in with 11.

back to our formula:

putting into my calculator gives me:
