Question

PLEASE HELP!!
I need to find the equation for this graph. I already did most of the work!

Answer 1

I already know that it is going to be Negative and that the vertex is at (3,1). The vertex would be h and k, which are in the vertex formula.
To find x and y, I need to pick a point on the parabola that can't be the vertex. I chose (2,1),

Answer 2

So now the equation looks like this. I'm just not sure what to do next.
