Answer:
Point C
Step-by-step explanation:
If you retrieve 90 backwards, then you will get the point C.
 
        
             
        
        
        
In linear models there is a constant additve rate of change. For example, in the equation y = mx + b, m is the constanta additivie rate of change.
In exponential models there is a constant multiplicative rate of change.
The function of the graph seems of the exponential type, so we can expect a constant multiplicative exponential rate.
We can test that using several pair of points.
The multiplicative rate of change is calcualted in this way:
 [f(a) / f(b) ] / (a - b) 
Use the points given in the graph: (2, 12.5) , (1, 5) , (0, 2) , (-1, 0.8)
[12.5 / 5] / (2 - 1) = 2.5
[5 / 2] / (1 - 0) = 2.5
[2 / 0.8] / (0 - (-1) ) = 2.5
Then, do doubt, the answer is 2.5 
        
                    
             
        
        
        
8, because the factors of 8 are 1,2,4,8, while the multiples of 8 start with 8,16,24, etc
