Answer:
(9, 3 )
Step-by-step explanation:
under a reflection in the y- axis
a point (x, y ) → (- x, y ) , then
(- 9, 3 ) → (9, 3 )
 
        
             
        
        
        
<u>Answer:  </u>
Sum of the roots of the polynomial 
<u>Solution:</u>
The general form of cubic polynomial is  ---- (1)
 ---- (1)
If we have any cubic polynomial  having roots
 having roots 
Sum of roots  =
 =  ---(2)
 ---(2)
From question given that,
 --- (3)
 --- (3)
On comparing equation (1) and (3), we get a = 1, b = 2, c = -11 and d = -12
Hence the sum of roots using eqn 2 is given as,
=  
 
= -2
Hence the sum of the roots of the polynomial 
 
        
             
        
        
        
A because that is where they cross
