Explanation Given: f ( x ) = − x 2 + 4 x + 5 Formula used: The graph of the quadratic equation f ( x ) = a x 2 + b x + c , a ≠ 0 is a parabola with vertex at ( − b 2 a , f ( − b 2 a ) ) . Calculation: The given equation is f ( x ) = − x 2 + 4 x + 5 . For the quadratic function f ( x ) = − x 2 + 4 x + 5 , we have a = − 1 , b = 4 and c = 5 ...
