Answer 2

Answer:

-7 and -25

A and C are correct

Step-by-step explanation:

The graph of a certain quadratic function has no x-intercepts.

As we know if graph has no x-intercept then complete graph either above x-axis or below x-axis.

The zeros of this quadratic function are imaginary.

Discriminant = D

$y=ax^2+bx+c$

$D=b^2-4ac$

D must be negative for imaginary zeros.

In the given options A=-7 and C=-25 are negative.

Hence, -7 and -25 are discriminant which has no x-intercept.
