I believe
q = -1
p = -2
when so x = 0 y = -4.

It's a quadratic in completed the square form. That is, the maximum point occurs at , alerntively:

, so the intersection with the x-axis is when .

You know that this point occurs at . So... . (i.e: your graph clearly shows that when y=0 (the x-axis), we have x=2)

Furthermore, you know that when we have that , so: where you substitute in your value for that you found above.

therefore, q = -1 and p = -2, right? thanks for your various solutions/workings, I see you giving answers often
