part a: write functions to represent the number of homes in neighborhood a and neighborhood b throughout the years. (4 points)
part b: how many homes does neighborhood a have after 5 years? how many does neighborhood b have after the same number of years? (2 points)
part c: after approximately how many years is the number of homes in neighborhood a and neighborhood b the same? justify your answer mathematically. (4 points)
a)
f(x)=30*0.2x
f(x)=45+3x
b)
f(x)=30+0.2(5)=31
f(x)=45+3(5)=60
c)
