A)

f ( x ) = \left\{ \begin{array} { l l } - 2 x & \text { if } x \leq 1 \\ x + 2 & \text { if } x > 1 \end{array} \right.

; Domain:

( \infty , 2 ) \cup ( 2 , \infty )

, Range:

( \infty , \infty )

f ( x ) = \left\{ \begin{array} { l l } - x & \text { if } x \leq 1 \\ 2 x + 1 & \text { if } x > 1 \end{array} \right.

Domain:

( \infty , \infty )

, Range:

( \infty , 2 ) \cup ( 2 , \infty )

f ( x ) = \left\{ \begin{array} { l l } - 2 x & \text { if } x \leq 1 \\ x + 1 & \text { if } x > 1 \end{array} \right.

; Domain:

( \infty , \infty )

, Range:

( \infty , \infty )

f ( x ) = \left\{ \begin{array} { l l } 2 x & \text { if } x \leq 1 \\ x + 1 & \text { if } x > 1 \end{array} \right.

; Domain:

( \infty , \infty )

, Range:

( \infty , \infty )
