Chang 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 24 2 12 3 6 4 3 Which function best shows the relationship between n and f(n)? f(n) = 48(0.5)n − 1 f(n) = 24(0.5)n f(n) = 24(0.5)n − 1 f(n) = 48(0.5)n + 1
