Question 4 of 25

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. 0
B. -25
C. 18
D. -7

Answer 1

A.) 0

Explanation:

It determines the number of times the graph crosses the x-axis. Discriminant > 0: the graph crosses the x-axis twice Discriminant = 0: the graph touches the x-axis at its maximum or minimum point Discriminant < 0: The graph has no x-intercepts, which means it is wholly above or below the x-axis
