A....if its wrong im sorry but i believe its a because you will do 4x4 and will get the sum of 16ft square 
        
             
        
        
        
Answer:
Q' (2,4) 
R' (3,1) 
S' (5,3)
Step-by-step explanation:
When reflected across x-axis, the x-values stay the same but y-values change signs. Because you count how many points till the reflection line then same amount you have to go to the other side. But since it is saying x-axis, the reflection line is on x=0 so you just change the sign.
 
        
                    
             
        
        
        
Turning points are inflection points
think
1st degree (linear) has no turning/inflecion points
2nd degree (quadratic, parabola) has  1 turning/inflection point
so
nth degree has n-1 turning/inflection point
this is 11th degree since highest power is 12
12-1=11
11 turning oints
