Suppose that the dynamics of a certain population of kangaroos is governed by a linear DTDS, with time measured in years and population measured at the end of the fall. We know that each year, natural net growth results in 1818% more kangaroos; but then a licenced hunting program removes 2727 kangaroos.

What is the updating function of the DTDS that describes the dynamics of this population?

Answer: f(x)=f(x)= __________
