A study on the population of wolves is being done in a county to determine how the number of wolves has changed over time. The population of wolves is being modeled by the function P(t) = 80(0.98)t, where t is the number of years since 2009.

What is an appropriate domain for this function if the study will end in the year 2020 and began in year 2000?

Fill in the blanks so that the appropriate domain is described.

Does P(t) = 80(0.98)t mean P(t) = 80 * (0.98)^t?

a1234 · Answer

Because that looks like an exponential growth problem.

well its exponential functions but yeah sounds right to me
