If x = 6 is the only x-intercept of the graph of a quadratic equation, which statement best describes the discriminant of the equation? The discriminant is 0.
The discriminant is 6.
The discriminant is positive.
The discriminant is negative.

the discriminant is 0

Step-by-step explanation:

the linear line isnt intersecting any other points on the graph because x is only one value

for example

lets substitute numbers into the quadratic equation;

1: 1=6 (1,6)

2: 2=6 (2,6)

3: 3=6 (3,6)

pretty much the line shows no increase nor decrease.

combine all like terms then its just a 2 step equation
