Ответ:
This model predicts that population will be 315,842 in 9 years.
Step-by-step explanation:
Let the population of the city be represented by the function
, where 
is the number of years from the present. The negative exponent means that such city is expected to experiment a sustained decrease. The predicted population in 9 years is determined by evaluating the function at 
:
