What type of an equation are u looking for y-x?
<u>ANSWER</u>

<u>EXPLANATION</u>
The vertex form of a parabola has equation:

where V(h,k) is the vertex of the parabola and 'a' is the leading coefficient.
From the question, we have that, the vertex is

and the leading coefficient is

We substitute the vertex and the leading coefficient into the vertex form to get:

We simplify to get:

The graph of this function is shown in the attachment.
