Which quadratic graph below has a negative discriminant?

The graph in (A)

Step-by-step explanation:

Negative discriminant of a quadratic function implies the corresponding quadratic equation ax^2+bx+c=0 does not have any real solutions (it still has solutions in the complex domain, however). Graphically, this corresponds to a parabola that never intersects the x axis for any value x, i.e. it lies either fully above or fully below the x axis. This situation is depicted in the case (A), where the parabola lies below the x axis and has no x-intercepts.

The cases (B), (C), and (D) all intersect the x axis in at least one point.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
