maximum equal to 9
=> f ' (x) = 0
=> 2ax + b = 0
=> x = - b/2a
=> a(- b/2a)^2+b(- b/2a)+c = 9
etc

And passes through WHAT points? You don't have to cram everything into the subject line, you know.
Anyway, this is going to be a parabola that opens downwards. Find an expression for the axis of symmetry. This is also the point where x=9. Use the other points to find the values for a, b, and c.

What points does the curve pass through?
Also, a similar question was answered in
this forum a few days ago!
Is this a class homework problem, perhaps?
