Standard 24: Exponential Growth Mastery Check

1. Given f(x) = 7(3)x, Find f(2) 2. Given f(x) = 153(1.35)x, Find f(4) 3. Given f(x) = 200(1.42)x, what is the initial value? In other words, what would be the y-intercept for this exponential function? 4. Given f(x) = 200(1.42)x, what is the growth rate? In other words, what is the percent of increase? 5. The population of Youngstown is 66,000. The population increases by 2% per year. Write an exponential function that models this situation. Write this equation in two ways.a. y =b. f(x) = Remember f(x) is function notation. 6. What will be the population of Youngstown in 6 years?
