Solve the problem.In 1995 the population of a certain city was 23,000. Since then, the population has been growing at the rate of 1.5% per year. Is this an example of linear or exponential growth? Find a function f that computes the population x years after 1995.
A. Linear; f(x) = 345x + 23,000 B. Exponential; f(x) = 23,000(1.015)x C. Exponential; f(x) = 23,000(0.015)x D. Linear; f(x) = 0.015x + 23,000
