find the maximum value of
The maximum value of a parabola, whose coefficient of x^2 is negative, is it's vertex.
This quadratic equation is in standard for:, our a=-1, b=6, and c=0.
The equation for finding the x value of a quadratic equation written in standard form is:
Plug that into the parabola for x and you'll find the maximum value.
The maximum value of this parabola is at (3,9).
Happy Calculating!!!

maximum value of y=-x^2 + 6x
----------
you have a quadratic with a=-1, b=6
the max is at x=-b/2a = -6/-2=3
Then f(3)=-(3)^2+6(3)=27
So the max is at (3,27)
