First Rewrite the Quadratic Function in Standard Form by Completing $$f ( x ) = - x ^ { 2 } + 17 x - 72$$

Multiple Choice

First rewrite the quadratic function in standard form by completing the square, then find any x-intercepts and any y-intercepts.
- $$f ( x ) = - x ^ { 2 } + 17 x - 72$$

A) $x$ -intercepts: 8 and $- 9 ; y$ -intercept: 17
B) $x$ -intercepts: $- 8$ and $- 9 ; y$ -intercept: 72
C) $x$ -intercepts: 8 and $9 ; y$ -intercept: $- 72$
D) No x-intercepts; y-intercept: $- 72$
