The average rate of change of on the interval [a,b] is:
 f(b)−f(a)/ b-a
or 
y1-y2/x1-x2 which is how I learned it, average ratw of change is just slope 
so you would plug your numbers into x
 1st the b: 6((1))^2+31((1))-12
 =6+31-12 1^2=1, so it cancels
 f(b) =25
2nd the a: 6((-2))^2+31((-2))-12
 =6(4)+31(-2)-12
 =24+-62-12
 f(a) =-50
3rd plug them in: (25- -50)÷(1-(-2)
 =75÷3
 =25
so your average rate of change(or slope) is 25 :)
        
             
        
        
        
The correct answer for this question is "<span>reflect over the y-axis, reflect over the x-axis, rotate 180°." In order to get to the expected transformation, first, flip it over the y-axis which cost 90 degrees of rotation. Then lastly, flip shape from 2nd quadrant over the y-axis. It will now be coincide with the transformation at the 3rd quadrant. Could I be brainlest... I'm a middle schooler who did this so...</span>
        
             
        
        
        
Answer:
Step-by-step explanation:
To move the graph 6 units to the right, subtract 6 in the absolute value. 
y=|x+5-6|
To move it up, add 2 outside the absolute value.
y=|x+5-6|+2
Now remove the absolute values since x>1.
y=x+5-6+2
y=x+1
