- $$f ( x ) = \frac { 1 } { x + 1 }$$

• A) Domain: \(( - \infty , - 1 ) \cup ( - 1 , \infty )\); Range: \(( 0 , \infty )\)
• B) Domain: \(( - \infty , - 1 ) \cup ( - 1 , \infty )\); Range: \(( - \infty , 0 ) \cup ( 0 , \infty )\)
• C) Domain: \(( - \infty , 1 ) \cup ( 1 , \infty )\); Range: \(( - \infty , 0 ) \cup ( 0 , \infty )\)
• D) Domain: \(( - \infty , 0 ) \cup ( 0 , \infty )\); Range: \(( - \infty , - 1 ) \cup ( - 1 , \infty )\)
