The vertex form will be: y=9(x-0)^2 -1

Explanation

The vertex form of any quadratic is : y= a(x-h)^2 +k where (h,k) is the vertex point.

Given equation is : y= 9x^2 -1

x^2 can be rewritten as (x)^2 or (x-0)^2

Thus,

$y=9x^2-1\\\\ y=9(x-0)^2 -1$

This equation is in form of y= a(x-h)^2 +k

So, the vertex form will be: y=9(x-0)^2 -1

take the -3 and add it to the 9 so it will make 12, so then ur left with 4x=12 divide the 4 from x by 12 and then you will be left with x=3
