Answer:
Part 1) The exponential function is 
Part 2) 
Step-by-step explanation:
Part 1) Write an exponential function
we know that
The exponential growth function is given by the formula

where
y is the population
x is the number of years
a is the initial population
r is the rate of change
we have

substitute


Part 2) How much will the population be after 16 years?
For x=16 years
substitute the value of x in the exponential function

Answer:
204
Step-by-step explanation:
Plug it into a calculator
