The vertex for any parabola expressed in standard form:
\ =\ ax^2\ +\ bx +\ c)
is at \right))
In your case 
, 
, and 
, so }{2(3)}\ =\ \frac{1}{3})
so
is at \right)\ =\ \left(\frac{1}{3},\ 3\left(\frac{1}{3}\right)^2\ -\ 2\left(\frac{1}{3}\right)\right))
You can do your own arithmetic to calculate the value of your function.
