When rabbits were first brought to Australia, they had no natural enemies. There were about
Why would an exponential equation be a better model for this situation than a linear one? Would a sine function be better or worse? Why?
Write an exponential equation for the number of rabbits
years after .
How many rabbits do you predict were present in
According to your model, in what year was the first pair of rabbits introduced into Australia? Is this reasonable?
rabbits were introduced in , so the model is not perfect, but is close. Is your exponential model useful for predicting how many rabbits there are now? Explain.
