Question 906366
Let f(x) = ax^2 + bx + c . Complete the square to write f in the form 
f(x) = 
------------------
y = ax^2 + bx +c
y = a(x^2 + (b/a)x) + c
----
Complete the square::
y = a(x^2 + (b/a)x + (b/2a)^2 + c-a(b/2a)^2
---
Factor:
y = a(x+(b/2a))^2 + c-a(b/2a)^2
--------------------
The graph of f is a parabola whose vertex has x = -b/(2a)____
------------------------------- 
If a < 0, then the __?__ value of 
f is f __?__
