where R is the growth rate, K is the carrying capacity, and xn is the population size at time n. Given fixed K, find the values of the growth rate R for which the population becomes extinct.

I would normally try to offer what I think I should do, but I am really clueless, so even a simple suggestion could put me in the right direction. Thanks for any help.
