A new apartment building was sold for $125000 5 years after it was purchased. The original owners calculated that the building appreciated $5000 per year while they owned it. Find a linear function that describes the appreciation of the building, if x is a number of years since the original purchase. F(x) = __________

Answer :

Given the following information:

Inital cost was $125000

loss $5000 in value after every year

Create a linear function

f(x)=

5000 was appreciated

[tex]\begin{gathered} 5000\times5=25000 \\ 125000-25000=100000 \end{gathered}[/tex]

f(x) = 5000x + 100000

(where x equals the numbers of years)
