discriminant must be minus cause the graph doesn't cross the x-axis .in other words it doesn't have an answer.plus , the "a" of the equation is minus too.
Answer:
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.
