Answer:
Option C and D
Step-by-step explanation:
For a quadratic function having no x-intercepts the discriminant should be less than 0 .

Now if this is less than zero if we plug in the values of a, b and c the square root of a negative number cannot be calculated thus giving us no real x-intercepts.

Here we can see that if we the value of D is less than zero the square would not be possible thus our correct choices are ,
