Write the new function.The linear function f(x) = 437x + 3420 provides an approximation of the annual cost (in dollars) of health insurance for a family of three, where  represents 1989,  represents 1990, and so on. Write a new function, g(x), that yields the same f(x)-values when the exact year number is entered.

A. g(x) = 437(1989 - x) + 3420
B. g(x) = 437(1988 - x) + 3420
C. g(x) = 437(x - 1988) + 3420
D. g(x) = 437(x - 1989) + 3420
