A certain region is losing about 18 million acres of rain forest each year.
a) find a linear function f that calculates the change in acres of rain forest in millions in x years.
b) find f(4) and iterpret the results

anonymous · Answer

since you want a linear function, it should look like this:  $\large f(x)=mx+b $

now you need to determine m = ???   and  b = ???
HINT:  m is the slope of the line and it describes the rate at which the line is changing.
