Exponential Verbal

The population of a small town is 1600 and is increasing at a rate of 3% per year. Write an exponential function to model this situation. Then find the population of the town after 10 years. (Verbal Question: How do we know this is growth or decay?)

• f(t) = 1600(1.03)^t; 2,150 people

• f(t) = 1600(0.97)^t; 1,738 people

• f(t) = 1600(1.03)^t; 2,128 people

• f(t) = 1600(0.97)^t; 1,819 people
