1. Determine a formula for the exponential function whose graph is shown in the figure. f(x) Y=/(x) (2, 6) 1(0, 3) . X 2. Population Growth Using 20th-century U.S. census data, the population of New York state can be modeled by 19.875 P(1) = 1 + 57.993e-0.035005r where P is the population in millions and f is the number of years since 1800. Based on this model, (a) What was the population of New York in 1850? (b) What will New York state's population be in 2015? 3. Bacterial Growth The number B of bacteria in a petri dish culture after / hours is given by B = 100e0.693+ (a) What was the initial number of bacteria present? (b) How many bacteria are present after 6 hr
