The average rate change of a function is given by the formula:
AG= (f(x_(2))-f(x_(1)))/(x_(2)-x_(1) )
So lets apply our formula to each one of our intervals:

For [-4,-2]

AV= (-12-0)/(-4-(-2)) =6

For [-2,1]

AV= (0-3)/(-2-1) =1

For [-3,1]

AV= (-5-3)/(-3-1) =2

For [-4,0]

AV= (-12-4)/(-4-0)=4

We can conclude that you should fill your table as follows:
[-4,-2]----->6

[-2,1]----->1

[-3,1]----->2

[-4,0]----->4
