Question

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. 0.013 4 76.8 307.2

Answer 1

average rate of change between x = a and x = b

\[\frac{ f(b)-f(a) }{b-a }\]

applying this logic to our problem, between day 11 and day 15, we use a = 11 and b = 15 to get

\[\frac{ f(15)-f(11) }{15-11}\]

calculate the appropriate values and evaluate this expression
