jim_thompson5910 · Answer

when x = 0, there is no change, so f(0) = 0

when x = 1, you lose 18 million acres, so f(1) = -18

jim_thompson5910 · Answer

In general, for any x, you lose 18x million acres which means that the function is f(x) = -18x

jim_thompson5910 · Answer

to find f(8), plug in x = 8 and evaluate

that would then be 144 million

jim_thompson5910 · Answer

yes, so after 8 years, you lose 144 million acres
