Hello :
let : 

calculate : x ......x <span>≠ -1 
</span>





the inverse function is : 

domain of : g  is the range of : f
as an interval : ]-∞: 3 <span>[</span>U ]3;+∞[
 
        
        
        
Combine like terms 
-6x^2+2y + -1 +2x^2 + -5y +3
( -6x^2+2x^2)+(2y-5y)+(-1+3)
= -4x^2+3y+2 
Answer : C 
I hope that's help !
 
        
             
        
        
        
Divide 4 by 1/10.
