question 90

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: \(( - \infty , 2 ) \cup ( 2 , \infty )\)
