f(x) - -11x^2 - 2x - 7

**Steve**, Thursday, December 1, 2011 at 2:29pmAll 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)
