Answer 1

B, D

Explanation:

If the discriminant has a positive value, there are two real roots. If it is 0, it has one real root (double root). If it is a negative value, then there are no real roots. When a quadratic function does not have x-intercepts, it has no roots and thus has a negative value for its discriminant.
