Answer:

A.-1

D.-18

Step-by-step explanation:

We are given that a graph of certain quadratic function has no x- intercept.

We have to find the possible values for the discriminant.

Consider a quadratic function

\(f(x)=x^2+1\)

x-Intercept:It is that integer value of x for which the value of function is equal to zero.

It has no x- intercept.

Discriminant:\(D=b^2-4ac\)

Where a=Coefficient of \(x^2\)

b=Coefficient of x

c=constant term

a=1, b=0,c=1

\(D=0-4(1)(1)=-4<0\)

When D<0 then, the function has no x- intercept.

Hence, the possible values for the discriminant are -1 and -18.

Option A and D are true.
