In 1983, the population of Functionville was 2560, and it tripled in 6 years.

a. Write an exponential model for the population of Functionville t years after 1983.

b. According to your model, it what year had the population grown to 7 times its size?

• Math -

since it tripled in 6 years, ew have

P = 2560*3^(t/6) where t=years since 1983

now plug in P=7, get t, add 1983 and voila'

• Math -

ahem. Plug in P=7*2560

I'm on the same problem and I'm having trouble solving it, can you go into a bit more detail.

• Math -

I'm confused
