y=-4x-9

Explanation:

Well, this depends on what your standard form is. The practical standard form of a second-power parabola would go like this: y=ax^2+bx+c . If you want to use this standard form, it will go like this:

y=x(x+2) -(x+3)^2

y = (x^2 +2x)-(x^2+6x+9)

y=-4x-9

So, in this problem, you have a basic, non-exponential form.
