Chang added some chlorine to the water in a pool. The chlorine evaporate in 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 10 weeks n |f(n)
1 | 24
2 | 12
3 | 6
4 | 3

Which function best shows the relationship between n and f(n)?

^ = To the power of

•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

This is high school algebra by the way
