Solve the problem.In 1995 the population of a certain city was 24,000. Since then, the population has been growing at the rate of 1% 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) = 24,000(0.01)x B. Exponential; f(x) = 24,000(1.01)x C. Linear; f(x) = 240x + 24,000 D. Linear; f(x) = 0.01x + 24,000
