A certain region is losing about 24 million acres of rain forest each year.

Question

(a) Find a linear function f that calculates the change in acres of rain forest in millions in x years. Type an expression using x as the variable f(x)=? (Type an expression using x as the variable.)

(b) Find f(4)=? (Simplify your answer.) and interpret the result ( After ? years, the region can expect to have lost about ? million acres of rain forest.

 

 

Answer 1

OK, Jamal, if it's still actual for you:

ƒ(x) = -24x
ƒ(4) = -24 · 4 = -96
After 4 years, the region can expect to have lost about 96 million acres of rain forest.
