A certain region is losing about 15 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)=

(b) Find f(8) and interpret the result ( After ? years, the region can expect to have lost about ? million acres of rain forest

Answer 1

   f(x) = -15x
   f(8) = - 120 ----> in 8 years, from this problem was written, rainforest will lose 120 millions acres

P. S. If it's true, we will lose so many species, and climate will be changed significantly! Too bad for us, humans.
