Answer:
You can use the function f(x) = 7(1 + 0.06)^8 to find the population after 8 years.
Explanation:
To find the population after 8 years using the function f(x) = abx, we need to plug in the values. In this case, the initial population (a) is 7, the growth rate (b) is 1 + 0.06 (which represents a 6% increase), and x is the number of years, which is 8. So, the function becomes f(8) = 7(1 + 0.06)^8.
