Question

a certain region is loosing about 13 million acres of rain forest each year.

A.Find a linear function f that calculates the change in acres of rain forest each year in millions in x years.

B.Find F (4) and interpret the result.

a. F(x)=
b.F(4)=
Interpret the results
After_ years, the region can expect to have lost about_ million acres of rain forest.

Answer 1

if the region loses 13 million acres of rain forest per year then its rate is -13x

f(x) = -13x

you can see, then, that in 1 year

f(1) = -13 million acres lost

in 2 years
f(2) = -26 million acres lost

in 3 years
f(3) = -39 million acres lost

etc., etc.

Answer 2

how would i type a an expression using x as the variable
