Step-by-step explanation:
x=5,11
y=8,8,11
Current population = P = 8742
Population after t years = A = 12000
Growth rate = r = 5%
We are to find the number of years it takes the population to grow to 12,000.
So, we can write:

Using the values, we get:
This means, it will take 6.492 years for the population to grow to 12,000.
