question 23

Multiple Choice

Use the graph of the function to find the domain and range of f.

• A) domain : \(( - \infty , - 2 ) \cup ( - 2 , \infty )\) range : \(( - \infty , - 2 ) \cup ( - 1 , \infty )\)
• B) \(\begin{array} { l } \text { domain : } ( - \infty , - 2 ) \cup ( - 2 , \infty ) \\ \text { range : } ( - 1,1 ) \end{array}\)
• C) \(\begin{array} { l } \text { domain : } ( - \infty , - 2 ) \cup ( - 2 , \infty ) \\ \text { range : } \{ - 2 , - 1 \} \end{array}\)
• D) domain : all real numbers range: \(( - 1,1 )\)
• E) domain : \(\{ - 2 , - 1 \}\) range : \(( - \infty , - 2 ) \cup ( - 2 , \infty )\)
