Answer: 
Step-by-step explanation:
Here, The function that describes the population of Florida after x years,
-------- (1)
Where a is the initial population of Florida and b is the growth factor.
Since, according to the table a = 17,385,430 and f(x) = 17,789,864
When x= 1
Thus, from equation (1),

⇒ b = 17,789,864/ 17,385,43= 1.0232628126≈ 1.023
By Putting the values of a and b in equation (1),
Required function is,
