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 rule, letting d=discriminant:

d>0, two real solutions

d=0, one real solution

d<0, no real solution (but there are two imaginary solutions)

So if it has only one real solution, the discriminant is equal to zero.

Step-by-step explanation:

A: The discriminant is 0.

I got it right in the quiz on edg.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
