Write the new function.The linear function f(x) = 72.66x + 1038 provides an approximation of the value (in dollars) of an account opened on January 1, 1988, in the amount of $1038 and earning 7% simple interest, where x = 0 represents January 1, 1988, x = 1 represents January 1, 1989, x = 2 represents January 1, 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) = 72.66(x - 1988) + 1038 B. g(x) = 72.66(1988 - x) + 1038 C. g(x) = 72.66(x - 1989) + 1038 D. g(x) = 72.66(1989 - x) + 1038
