Answer:

Step-by-step explanation:
Given

Interval: (-2,4)
Required
Determine the average rate of change
This is calculated using:

Where:

So, we have:



Calculate g(4) and g(-2)


So:



<em>Hence, the average rate of change is 1</em>
 
        
             
        
        
        
We would find it by multiplying:
(x -6) * (x +3) * (x -5) = 
x^3 -8x^2 -3x +90
