Barry has been watching the geese that live in his neighborhood. The number of geese changes each week. n f(n) 1 56 2 28 3 14 4 7 Which function best shows the relationship between n and f(n)? f(n) = 28(0.5)n f(n) = 56(0.5)n-1 f(n) = 56(0.5)n f(n) = 112(0.5)n-1

I am assuming that n-1 should actually be in brackets like (n-1) then when f(1) then you get 0 where if you use c then it comes out as 56

$$ f(1)=56\\ f(2)=28=\cfrac{f(1)}{2}\\\\ f(3)=14=\cfrac{f(2)}{2}=\cfrac{f(1)}{2^2}\\ f(4)=7=\cfrac{f(3)}{2}=\cfrac{f(1)}{2^3}\\ \cdots\\ f(n)=\cfrac{f(1)}{2^{(n-1)}}=\cfrac{56}{2^{(n-1)}}=56\left(\cfrac{1}{2}\right)^{n-1} $$ Does this make sense?
