Give the Domain and Range for the Rational Function $$f ( x ) = \frac { 1 } { ( x + 7 ) ^ { 2 } }$$

Multiple Choice

Give the domain and range for the rational function. Use interval notation.
- $$f ( x ) = \frac { 1 } { ( x + 7 ) ^ { 2 } }$$

A) Domain: $( - \infty , - 7 ) \cup ( - 7 , \infty )$ ; Range: $( - \infty , 0 ) \cup ( 0 , \infty )$
B) Domain: $( - \infty , 7 ) \cup ( 7 , \infty )$ ; Range: $( - \infty , 0 ) \cup ( 0 , \infty )$
C) Domain: $( - \infty , - 7 ) \cup ( - 7 , \infty )$ ; Range: $( 0 , \infty )$
D) Domain: $( - \infty , - 7 ) \cup ( - 7 , \infty )$ ; Range: $( - \infty , \infty )$
