F(x) = -4x^2+12x-9f(x)=−4x 2 +12x−9f, left parenthesis, x, right parenthesis, equals, minus, 4, x, squared, plus, 12, x, minus, 9 What is the value of the discriminant of fff? How many xxx-intercepts does the graph of fff have?

The graph has only one x-intercept

Step-by-step explanation:

we have

we know that

The discriminant of a quadratic equation of the form

is equal to

in this problem we have

so

substitute

The discriminant is zero

That means ----> The quadratic equation has one real solution

The graph has only one x-intercept

what are the statments
