The Kermack-Mckendrick model for infectious disease transmission can be used to predict the population size Pas a function of the disease's virulence (that is, the extent to which the diseases people). The population size P is large when virulence is low and it is also large when virulence is high because the disease kills people so fast that very few people get infected. For a specific choice of
parameter values, the population size is
P(v)=10+v+v^2/1+v 0
Find the largest population size and the virulence values v for which it occurs. (Round your answer for P to the nearest person. Round your answer for v to two decimal places. I needed, enter your
answers as comma-separated lists. If an answer does not exist, enter DNE.)

Find the smallest population size and the virulence values v for which it occurs
