3. 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 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?
