The population of a newly introduced species of insect in a contained ecosystem can be modelled by a twice-differentiable function $P(t)$, where $t$ is the time in weeks since introduction. The graph of $P’(t)$, the rate of change of the population, is shown below.
[Assume graph of P’(t) is provided here: A curve that starts at P’(0) = a (positive value), increases to a maximum, then decreases, crossing the t-axis at t=b and becoming negative, before tending towards zero as t approaches infinity.]
Assume $P(0) = c$, where c is a positive constant.
a. Describe the behaviour of the insect population during the time interval $[0, b]$. Justify your answer with reference to the graph of $P’(t)$.
