Question 476

Multiple Choice

Give the domain and range of the relation.
- Give the domain and range of the relation. -  A)  domain:  ( - \infty , \infty )  ; range:  ( - \infty , - 2 )  \cup ( - 2 , \infty )   B)  domain:  ( - \infty , \infty )  ; range:  ( - \infty , \infty )   C)  domain:  \{ - 2 \} ; range:  ( - \infty , \infty )   D)  domain:  ( - \infty , \infty )  ; range:  \{ - 2 \}


A) domain: (−∞,∞) ( - \infty , \infty ) ; range: (−∞,−2) ∪(−2,∞) ( - \infty , - 2 ) \cup ( - 2 , \infty )
B) domain: (−∞,∞) ( - \infty , \infty ) ; range: (−∞,∞) ( - \infty , \infty )
C) domain: {−2}\{ - 2 \} ; range: (−∞,∞) ( - \infty , \infty )
D) domain: (−∞,∞) ( - \infty , \infty ) ; range: {−2}\{ - 2 \}
