Cody Johnson's crowd at his first concert was 2,500 people. Over the years his crowds have grown exponentially. In fact, they have increased at an average rate of 8.2% per year. Which exponential function best describes Cody Johnson's success?
f(x) = 2500 (1.082)
f(x) = 8.2 (2500)
f(3) = 2500 (8.2)
f(x) = 2500 +1.0822
