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
Scorpion4ik [409]
<span> 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
</span>f(x) = 5340(1.75)^x where 1.75 is the rate of growth 
so D is right answer
