infinityAnswer: 
p(0) = 20
p(5) = 59 
Horizontal Asymptote: y = 2400 as t approaches infinity 
Explanation: 
part C. 
To find the horizontal asymptote, we investigate the behaviour of the function p(t) as t approaches infinity. 
Now as t approaches inifinty 

the terms 0.04 t and 0.01t become extremely large; so large in fact that we can ignore constant 3 and 1 to get 


which means at t -> ∞, p(t) = 2400. In the context of insect population this means that if we wait a long enough time, eventually the insect population will stop decreasing and approach 2400. In other words, the population limit is 2400 insects
