Answer:

The equation can be shown by the function f(x) = 4000 + 272x; where x is the number of the year.

Step-by-step explanation:

Total investment of Kevin is $4000.

The annual interest rate is 6.8%.

At the end of each year, [tex]\frac{4000\times6.8}{100} = 40\times6.8 = 4\times68 = 272[/tex] will be added with the amount.

Thus, at the end of x year $272x will be added.

The amount of money at the end of x year will be $(4000 + 272x).
