Use the Graph of the Function to Find the Domain $f$

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) domain: $( - \infty , - 2 ) \cup ( - 2 , \infty )$
range: $\{ - 2 , - 1 \}$
C) domain : all real numbers
range: $\{ - 2 , - 1 \}$
D) domain : $( - \infty , - 2 ) \cup ( - 2 , \infty )$
range: $( - 1,1 )$
E) domain: $\{ - 2 , - 1 \}$
range: all real numbers
