Final answer:
The range of the function a(m), representing the amount Fernando still owes after making m payments, is given by the expression a(m) = 7,200 - 200m. The range of values for a(m) spans from $7,200 to $0 as Fernando makes more payments.
Step-by-step explanation:
The range of the function a(m) represents the amount Fernando still owes, in dollars, after making m payments. In this case, Fernando borrowed $7,200 and will make 36 monthly payments of $200. We can determine the amount Fernando still owes after making m payments by subtracting the total payments made from the total amount owed.
Therefore, the range of the function a(m) is given by:
a(m) = 7,200 - 200m
where m represents the number of payments made. So, as Fernando makes more payments, the amount he still owes decreases, resulting in a range of values from $7,200 to $0.
