A)

f ( x ) = \left\{ \begin{array} { l l } 4 & \text { if } x < 0 \\ - 4 x & \text { if } x \geq 0 \end{array} ; \right.

Domain:

( - \infty , 0 ) \cup \{ 4 \}

, Range:

( - \infty , \infty )

f ( x ) = \left\{ \begin{array} { l } 4 \text { if } x < 0 \\ x \text { if } x \geq 0 \end{array} ; \right.

Domain:

( - \infty , 0 ] \cup ( 4 )

, Range:

( - \infty , \infty )

f ( x ) = \left\{ \begin{array} { l l } 4 & \text { if } x \leq 0 \\ - x & \text { if } x > 0 \end{array} ; \right.

Domain:

( - \infty , \infty )

, Range:

( - \infty , 0 ) \cup \{ 4 \}

f ( x ) = \left\{ \begin{array} { l l } 4 & \text { if } x < 0 \\ - x & \text { if } x \geq 0 \end{array} ; \right.

Domain:

( - \infty , \infty )

, Range:

( - \infty , 0 ] \cup \{ 4 \}

Give the Domain and Range of the Relation {(2,2),(−3,−3),(−6,−6),(6,6)}\{ ( 2,2 ) , ( - 3 , - 3 ) , ( - 6 , - 6 ) , ( 6,6 ) \}{(2,2),(−3,−3),(−6,−6),(6,6)}
