In a certain state, 3900 acres of farmland are being developed into housing developments per year. Create a function, $\mathrm{f}(\mathrm{x})$, that models the acres of farmland lost to development in $\mathrm{x}$ years.
A) $f(x)=2190 x$
B) $f(x)=-3900 x$
C) $f(x)=-2190 x$
D) $f(x)=3900 x$

Quizplus · Accepted Answer

The function $f(x)=3900x$ correctly models the acres of farmland lost to development in $x$ years, as it multiplies the annual loss (3900 acres) by the number of years ($x$).

In a Certain State, 3900 Acres of Farmland Are Being f(x)\mathrm{f}(\mathrm{x})f(x)
