Becky has been tracking the population of a town. The population was 5,340 last year and has been increasing by 1.75 times each year. How can Becky develop a function to model this?

A. f (x) = (5340 • 1.75) ^x where 1.75 is the rate of growth

B. f (x) = 1.75 (5340) ^x where 5340 is the rate of growth

C. f (x) = 5340 (x) ^1.75 where 5340 is the rate of growth

D. f (x) = 5340 (1.75) ^x where 1.75 is the rate of growth

Aron Perry · Answer 1

the population grows at rate of 1.75

multiply it by this rate every year

As in year 3 it would be 5340 (1.75) (1.75) (1.75) the function is 5340 (1.75) ^x

f (x) = 5340 (1.75) ^x where 1.75 is the rate of growth

so D is right answer
