Put your function into standard, namely \ =\ ax^2\ +\ bx\ +\ c)
, form.
The 
-coordinate of the vertex is given by 
The 
-coordinate of the vertex is the value of the function at the -coordinate of the vertex, to wit:
\ =\ f\left(\frac{-b}{2a}\right))
The line of symmetry is the equation 
The maximum or minimum value of the function is )
. It is a minimum if the lead coefficient (the 
in 
) is positive and a maximum if it is negative.
