1) The population of lions in a wildlife reserve can be modelled by the function f(x) = 1000 + 600x/10 + 0.6x , f(x) is the population of lions and x is the number years since the population was introduced. By this model, what does the vertical asymptote represent exactly?

a) The maximum number of lions that can survive in the reserve at any time.

b) Time which lions began living in reserve.

c) Nothing because the vertical asymptote is outside the domain.

d) Nothing because the verrtical asymptotes are irrelevant.

2) The population of lions in a wildlife reserve can be modelled by the function f(x) = 1000 + 600x/10 + 0.6x, f(x) is the population of lions and x is the number of yrs since the population was intro-duced. From the model what is the domain?
