(a) Explanation Definition used: The graph of the function f ( x ) = a ( x − h ) 2 + k is a parabola then, 1. It opens up if a > 0 and down if a < 0 . 2. ( h , k ) is the vertex. 3. x = h is the axis of symmetry. 4. k is the minimum value if a > 0 . 5. k is the maximum value if a < 0 . Calculation: The given function is f ( x ) = − x 2 − 8 x + 5 . Use the completing square method to convert the function f ( x ) = − x 2 − 8 x + 5 into the form f ( x ) = a ( x − h ) 2 + k . f ( x ) = − x 2 − 8 x + 5 = − ( x 2 + 8 x ) + 5 = − ( x 2 + 8 x + 16 − 16 ) + 5 ( add and subtract 16 ) = − ( x + 4 ) 2 − ( − 16 ) + 5 (b) To determine The axis of symmetry of the function f ( x ) = − x 2 − 8 x + 5 . (c) To determine To find: The maximum or minimum value of the function f ( x ) = − x 2 − 8 x + 5 , if it exists. (d) To determine To sketch: The graph of the function f ( x ) = − x 2 − 8 x + 5 .
