The leading coefficient is positive, so the parabola opens upward. It will be positive up to the left-most zero, and positive again to the right of the right-most zero. That is, the function is positive everywhere outside the interval [-2, 3], where it is not.
Looking at the image, there are 2 grey squares and 1 black square. Since the question is asking how many black squares to grey squares, it would be a 1:2.
