Multiple Choice

Graph the function on your calculator to determine the domain and range from the graph.
- $$f ( x ) = \frac { 1 } { x } + 2$$

A) Domain: $( - \infty , \infty )$ ; range: $( - \infty , 0 ) \cup ( 0 , \infty )$
B) Domain: $( - \infty , 0 ) \cup ( 0 , \infty )$ ; range: $( - \infty , 0 ) \cup ( 0 , \infty )$
C) Domain: $( - \infty , \infty )$ ; range: $( - \infty , \infty )$
D) Domain: $( - \infty , 0 ) \cup ( 0 , \infty )$ ; range: $( - \infty , 2 ) \cup ( 2 , \infty )$
