danjs · Answer

$$f(x) = a *b^x$$

danjs · Answer

x = time  which i guess must be greater or equal to zero

a = starting population, principal amount

b = rate of growth

danjs · Answer

when time is zero, a*b^0  =  a  

the starting amount, the domain is all time, x >0

danjs · Answer

the resulting rage is all the possible populations, a to infinity
