Answer:
Option C. negative
Step-by-step explanation:
we know that
In a quadratic equation of the form
[tex]ax^{2} +bx+c=0[/tex]
The discriminant is equal to
[tex]D=(b^{2}-4ac)[/tex]
If D=0 ----> then the system has only one real solution
If D > 0 ---> the the system has two real solutions
If D < 0 ---> then the system has complex solutions
The quadratic equation of the graph has complex solutions
therefore
The discriminant is negative
