Multiple Choice

First rewrite the quadratic function in standard form by completing the square, then find any x-intercepts and any y-intercepts.
- $$f ( x ) = 2 x ^ { 2 } + 10 x - 48$$

A) $x$ -intercepts: 6 and 4 ; No $y$ -intercepts
B) x-intercepts: 6 and $- 4 ; y$ -intercept: $- 10$
C) $x$ -intercepts: $- 8$ and 3 ; $y$ -intercept: $- 48$
D) $x$ -intercepts: $- 8$ and $- 3 ; y$ -intercept: 48
