(D) The given equation of the parabola is $y^2 + 2y + x = 0$. Completing the square for the $y$ terms: $(y^2 + 2y + 1) - 1 + x = 0$ $(y + 1)^2 = -(x - 1)$ Comparing this with the standard form $(y - k)^2 = -4a(x - h)$,we get the vertex $(h, k) = (1, -1)$. Since the $x$-coordinate is positive and the $y$-coordinate is negative,the point $(1, -1)$ lies in the $IV$ quadrant.

The vertex of the parabola $y^2 + 2y + x = 0$ lies in which quadrant?
