i think its d, 36. Am i right?
A graph does not have discriminant. We call discriminant to this: \[\sqrt{b^2-4ac}\]
yea but dont u have to figure it out somehow?
this is what i did, hold on

That graph represents a quadratic function which roots depends on the value of the determinant.
x = -4 and x = 2 So, (x - 4) (x + 2) = 0 -4 * 2 = - 8 and - 4 + 2 = -2 y = x^2 - 2x - 8 b^2 - 4ac (-2)^2 - 4(1)(-8) 4 + 32 =36 Discriminate, SO you have to work backwards, am i right?
As you can see there are two different roots, and there are real numbers. So the value of the discriminant must be positive.
Exactly, you''re right!
so d?
