The graph of a certain quadratic function has no x-intercepts. which of the following are possible values for the discriminant? check all that apply.
a. -1

b. 3

c. 0

d. -18

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

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:

Where a=Coefficient of

b=Coefficient of x

c=constant term

a=1, b=0,c=1

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.
