Question

Use the discriminant to determine the number of x-intercepts of the graph: 
A) One 
B) Two 
C) None

Quizplus · Accepted Answer

The discriminant is the part under the square root in the quadratic formula, which is b^2-4ac. If the discriminant is greater than 0, there are two x-intercepts, if it equals 0, there is one x-intercept, and if it is less than 0, there are no x-intercepts. Without the specific quadratic equation provided, we cannot calculate the discriminant, so the answer must be C, which indicates that we cannot determine the number of x-intercepts.
