Answer:
The graph has only one x-intercept
Step-by-step explanation:
we have
![f(x)=-4x^2+12x-9](https://tex.z-dn.net/?f=f%28x%29%3D-4x%5E2%2B12x-9)
we know that
The discriminant of a quadratic equation of the form
is equal to
in this problem we have
![f(x)=-4x^2+12x-9](https://tex.z-dn.net/?f=f%28x%29%3D-4x%5E2%2B12x-9)
so
![a=-4\\b=12\\c=-9](https://tex.z-dn.net/?f=a%3D-4%5C%5Cb%3D12%5C%5Cc%3D-9)
substitute
The discriminant is zero
That means ----> The quadratic equation has one real solution
The graph has only one x-intercept
Answer:
A closed dot represents a lreater than or equal to or less than or equal to, which can be distinguished in an inequaity's equation by an underline.
Step-by-step explanation:
The number "4" is in the hundreds place. To the right is 7, and since it's greater than five it rounds up. So 16,473 to the nearest hundred is 16,500. Hope this helped!
3x is the least common denominators because you need to be able to make sure all other denominators can go multiple into it. Since the rest are just x, the largest number of 3x would be the denominator you want.
