Write the new function.The linear function f(x) = 225x + 6320 provides an approximation of the annual cost (in dollars) to rent an apartment at the Leisure Village Retirement Community, where x = 1 represents 1979, x = 2 represents 1980, 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) = 225(1979 - x) + 6320 B. g(x) = 225(x - 1978) + 6320 C. g(x) = 225(1978 - x) + 6320 D. g(x) = 225(x - 1979) + 6320
