Analyzing Exponential Functions (2.5.1) November 8th, 2016

Exponential Growth and Decay Functions For each of the functions below, label the meaning of each variable . What is the major difference between growth and decay? Exponential Growth: Exponential Decay:

Ex: (a)The population of armadillos in Texas since the year 2000 is modeled by the equation where t is the time in years that has passed since the year 2000. Is this a growth or a decay model? How many armadillos were there in 2000? What is the yearly rate of change of the population? (b) The population of kangaroos in New Zealand since 2000 is modeled by the equation . Is this a growth or decay model? How many kangaroos were there in 2000? What is the yearly rate of change of the population?
