Bruce added some chlorine to the water in a pool. the chlorine evaporated at a fixed rate every week. the table below shows the amount of chlorine f(n), in ounces, that was left in the pool after n weeks: n f(n) 1 54 2 27 3 13.5 4 6.75 which function best shows the relationship between n and f(n)?
f(n) = 108(0.5)n−1
f(n) = 54(0.5)n
f(n) = 108(0.5)n+1
f(n) = 54(0.5)n−1
