I think the correct exponential model would be #y = 5*1.44^x#?


Most population problems utilize an exponential model #y = a*b^x# for the equation. In order to find the initial population, the number that is the multiplier "a", is the initial population. It could be 5 million or just five. (You need to get the units from the problem)

Algebraically, you can also substitute x = 0 for the amount of time that has passed (initial time = 0), thus giving #y = 5*1.44^0#, or y = 5.
