Question 11 of 25The 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.3B.-1C.-18D.0
Solution
The discriminant of a quadratic equation is found using the formula D = b² - 4ac. If the graph of the quadratic function has no x-intercepts, it means the parabola does not cross the x-axis, which implies that there are no real roots. This happens when the discriminant is less than zero.
So, the possible values for the discriminant in this case are:
B. -1 C. -18
These are the only values that are less than zero.
