Curve is crossing x-axis at two points ⇒ roots are real ⇒ b 2 − 4 a c > 0 Roots are of opposite signs c / a < 0 ⇒ c < 0 Also magnitude of +ve root is larger ⇒ sum of roots > 0 ⇒ − b / a > 0 ⇒ b < 0 Hence all the options are correct. To compare them, we can formally look at the rate of decrease--meaning the change in y over the change in x. I'm pretty sure c is the y-intercept, and I think b is used to partially calculate the turning point.

Before we get into the meat of the lesson, let's go over just a couple of definitions. That's to be expected with the equation for "vertical" parabolas that you described. I'm dealing with quadratic equations (y=ax2+bx+c) and I need to know what the three variables, a, b and c stand for.
