$V(1. -3)$ . See Socratic graph.

y=9x^2-6x, and in the standard form, this is

$(x-1)^2=1/3(y+3)$ , revealing

vertex at V(1, -3),

axis along $x = 1 uarr$ .

size $a =1/12$ and

focus at $S(1, -35/12)$

graph{(3x^2- 6x-y)((x-1)^2+(y+3)^2-.01)=0x^2 [-10, 10, -5, 5]}

What is the vertex of y= 5x^2-2x-1+(2x-1)^2 y= 5x^2-2x-1+(2x-1)^2?
