Answer:

a. Negative discriminant: above  

b. Positive discriminant:  below

c. Discriminant is zero: on

Step-by-step explanation:

If the discriminant is negative, then there are no real zeros. We have an upward-facing parabola, then the vertex is located above the x-axis

If the discriminant is positive, then there are two different real zeros. We have an upward-facing parabola, then the vertex is located below the x-axis

If the discriminant is zero, then there is one zero. We have an upward-facing parabola, then the vertex is located on the x-axis
