Answer:
80,000 will be the population in 42 years. It is an exponential function.
Step-by-step explanation:
If a town with a population of 10,000 doubles every 14 years.
Initial population of a town is 10,000
Point: (0,10000)
It's double every 14 years.
Point: (14,20000)
Let us suppose exponential function
Now using both point to find a and b
Using point (14,20000) and a=10000 to solve for b
Exponential function:
We need to find y at x=42
So, we put x=42 into function and solve for y
y=80,000
Thus, 80,000 will be the population in 42 years. It is an exponential function.
