anonymous · Answer

is it 
$$f(x)=11(1.35)^x$$?

geekfromthefutur · Answer

yea :D

anonymous · Answer

i assume first year is actually year zero and fifth year is  $x=4$ your job is to compute 
$$\frac{f(4)-f(0)}{4-0}$$

oh ok

anonymous · Answer

i get this http://www.wolframalpha.com/input/?i=%2811*%281.35%29^4-11%29%2F4

anonymous · Answer

it is an average because the denominator is the number of years (4) and the numerator is the ending amount minus the initial amount

geekfromthefutur · Answer

oh ok but this isnt a multiple chose it says i have to round f(x)= 11(1.25)^x
