given the following quadratic equation, determine if it has a maximum or a minimum value. Then find the maximum or minimum value
f(x) - -11x^2 - 2x - 7
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
-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.
