A city's population is approximated by

f(t)=900\cdot 2^t

, where

t

is years. A demographer uses the inverse to determine when the population reaches a target value. Here,

f(t)

is the population after

t

years and 900 is the initial population. The base 2 indicates doubling per year in this model. What is the inverse of

f(t)
