Write the new function.The linear function f(x) = 473x + 3420 provides an approximation of the annual cost (in dollars) of health insurance for a family of three, where 
represents 1993, 
represents 1994, 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) = 473(1992 - x) + 3420 B. g(x) = 473(1993 - x) + 3420 C. g(x) = 473(x - 1993) + 3420 D. g(x) = 473(x - 1992) + 3420
