Answer:
Step-by-step explanation:
1) Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.
2) The vertex of a parabola is the point at the top or bottom of the parabola.
3) 'h' is -6, the first coordinate in the vertex.
4) 'k' is -4, the second coordinate in the vertex.
5) 'x' is -2, the first coordinate in the other point.
 
        
             
        
        
        
Answer: -12 but could be wrong
Step-by-step explanation:
I don't know that format but I'm going to take a guess. 
x^2 +2x - 8 -(2x+8) then plug in x=2
x^2 + 2x - 8 - 2x - 8
x^2 -16
= 2^2 - 16 = -12
 
        
             
        
        
        
You can work it out by using trial and error
so you get
x=3 , y=2
