Answer:
The y intercept for the equation is (0,-7)
 
        
             
        
        
        
Well let's say x = -1000 
That's what I would do
        
                    
             
        
        
        
Answer: y = -2/3(x-3)^2 + 0 or y = -2/3(x-3)^2
Step-by-step explanation:
vertex form is y=a(x-h)^2 + k
here we can see the vertex is (3,0) which is (x,y). Or (h,k) in this case.
so to plug that into vertex form, we now have y=a(x-3)^2 + 0. or just y=a(x-3)^2.
now we need to find "a" which is the leading coefficient. to do that we can plug in the (6,-6) for the x and y parts of the above equation. so we'd have
 -6=a(6-3)^2. which goes to -6=a(2)^2 which is -6=4a. divide each side by 4 to get a = -2/3. plug this in for a 
the final equation would be y = -2/3(x-3)^2 + 0 or y = -2/3(x-3)^2
 
        
             
        
        
        
0,-2 is the answer i believe
