All quadratics have a maximum or minimum value. You must want to know whether it has a minimum or a maximum.
Can't tell from your posting whether the function is
11x^2  2x  7
or
11x^2  2x  7
The first has a minimum (at x = 1/11), the second has a maximum (at x = 1/11).
Plug in the proper x to get the value of f(x)

sorry about that, it was the second one. Thank you, I figured it out and also got 1/11 so feel better knowing it is right.
