Write the new function.The linear function f(x) = 76.51x + 1093 provides an approximation of the value (in dollars) of an account opened on January 1, 1997, in the amount of $1093 and earning 7% simple interest, where x = 0 represents January 1, 1997, x = 1 represents January 1, 1998, x = 2 represents January 1, 1999, 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) = 76.51(x - 1997) + 1093 B. g(x) = 76.51(x - 1998) + 1093 C. g(x) = 76.51(1998 - x) + 1093 D. g(x) = 76.51(1997 - x) + 1093
