Determine a Quadratic Function's Minimum or Maximum Value
Determine whether the given quadratic function has a minimum value or maximum value. Then find the
coordinates of the minimum or maximum point.
- $$f ( x ) = - 4 x ^ { 2 } + 4 x$$

A) maximum; $\left( \frac { 1 } { 2 } , 1 \right)$
B) minimum; $\left( \frac { 1 } { 2 } , 1 \right)$
C) minimum; $\left( - \frac { 1 } { 2 } , - 1 \right)$
D) maximum; $\left( - \frac { 1 } { 2 } , - 1 \right)$
