Multiple Choice

Identify intervals on which the function is increasing, decreasing, or constant.
- $$f ( x ) = 0.5 ( x + 4 ) ^ { 2 } - 7$$

A) Increasing: $( - \infty , - 0.5 )$ ; decreasing: $( 0.5 , \infty )$ ; constant: $( - 0.5,0.5 )$
B) Increasing: $( 4 , \infty )$ ; decreasing: $( - \infty , - 4 )$ ; constant: $( - 4,4 )$
C) Increasing: $( - 4 , \infty )$ ; decreasing: $( - \infty , - 4 )$
D) Increasing: $( - \infty , - 4 )$ ; decreasing: $( - 4 , \infty )$
