Solve the problem.During 1991, 200,000 people visited Rave Amusement Park. During 1997, the number had grown to 834,000. If the number of visitors to the park obeys the law of uninhibited growth, find the exponential growth function that models this data.
A. f(t) = 200,000e0.238t B. f(t) = 634,000e0.238t C. f(t) = 200,000e0.248t D. f(t) = 634,000e0.248t
