Question 293019: A herd of 100 deer is introduced to a small island. The herd at first increases rapidly, but eventually the food resources of the island dwindle and the population declines. Suppose that the number N(t) of deer after t years is given by . When does the population of deer become extinct on this island?

*note* we are working with max/min quadratic problems currently. I tried getting the factors of p and q and doing synthetic division. I'm just confusing myself more. I'm not sure where to start.

Thanks :)
