For which discriminant is the graph possible? b2 – 4ac = –12 b2 – 4ac = 0 b2 – 4ac = 7

A)

Step-by-step explanation:

1) To answer this question, we must remember what this discriminant stands for:

2) We must plug in this discriminant, in the square root of Quadratic  Formula, to find its roots, i.e.:

The discriminant is a radicand.

3) The graph above shows us no Real roots for this equation then we have roots ∈ Complex Numbers, in other words:

4) So, it's A.
