You have the correct min.

Isn't this the same question as this one?
Err exactly the same. The min is wrong >.<. The minimum value occurs at x = -2 but the minimum value is not -2.

Your parabola in standard form is
y = 2(x+2)^2 - 10 , (check it by expanding this)
so you have a parabola opening upwards with vertex at (-2,-10)
Minimum value is -10, when x=-2
axis of symmetry is x=-2
domain: any real number for x
range: y ≥ -10, y any real number
