The country of Benin in West Africa has a population of 9.05 million people. The population is growing at a rate of 3.1% each year. Which function can be used to find the population 7 years from now?
(1) f(t) = (9.05 x 10)(1 -0.31)^7
(2) ft) = (9.05 x 10)(1 + 0.31)^7
(3) ft) = (9.05 x 10^)(1 +0.031)^7
(4)f(1) = (9.05 x 10^)(1 -0.031)^7
