It sounds like it could be either one.
The x-coordinate of the vertex is at
where the equation looks like

The turning point is at (0,-7), so

Now I have

------------
It looks like can be any (+) or (-)
number since it just controls the shape
( narrow or wide ) and the direction
( open down or open up )
I'll say
answer
Here's the plot:
