In what they call "Year Zero," a group of 26 people started a settlement. Every year the population changes as babies are born, people move in, and people move out.
Generally, the population increases by an average of 2.6 people a year.
At the same time, a nearby established community discovered that their population
could be described by the following function, where f(x) is the population, in
people, and x is the time, in years, from "year zero."
f(x) = -5.3x + 256
Part A
Using your knowlekage of functions, explain specifically why both communities' ways
of expressing their populations represent functions. Provide evidence to support
your answer
Part B
Analyze the functions and compare the populations for the two communities over
time by describing in detail under what conditions one community's population is
greater than the other's population. Provide evidence to support your answer.
