Solve the problem.In 1995 the population of a certain city was 41,000. Since then, the population has been growing at the rate of 700 people per year. Is this an example of linear or exponential growth? Find a function f that computes the population x years after 1995.
A. Exponential; f(x) = 41,000(700)x B. Linear; f(x) = 700x + 41,000 C. Exponential; f(x) = 41,000(1.07)x D. Linear; f(x) = 41,000x + 700
