the answer:
the main formula for computing the multiplicative rate of change is given by:

Mutiplicative Rate of Change = [f(x2)/f(x1)]  / (x2 -x1)
this formula can be written as
 [f(x2)/f(x1)]  / (x2 -x1) = [f(x2) * (x2 -x1) /f(x1)] 

for example we can take (x1, f(x1))= (0, 2) and (x2, f(x2))= (1, 5) 
therefore,
Mutiplicative Rate of Change = [5/2]  / (1-0)= 5/2= 2.5

the answer is 2.5
