Question

Give a rule for the piecewise-defined function. Then give the domain and range.
-
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: $( - \infty , \infty )$ 
B) $f ( x ) = \left\{ \begin{array} { l } 4 \text { if } x < 0 \ x \text { if } x \geq 0 \end{array} ; \right.$ Domain: $( - \infty , 0 ] \cup ( 4 )$, Range: $( - \infty , \infty )$ 
C) $f ( x ) = \left\{ \begin{array} { l l } 4 & \text { if } x \leq 0 \ - x & \text { if } x > 0 \end{array} ; \right.$ Domain: $( - \infty , \infty )$, Range: $( - \infty , 0 ) \cup \{ 4 \}$ 
D) $f ( x ) = \left\{ \begin{array} { l l } 4 & \text { if } x < 0 \ - x & \text { if } x \geq 0 \end{array} ; \right.$ Domain: $( - \infty , \infty )$, Range: $( - \infty , 0 ] \cup \{ 4 \}$

The Answer of Give a rule for the piecewise-defined function. Then give the domain and range.
-
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: $( - \infty , \infty )$ 
B) $f ( x ) = \left\{ \begin{array} { l } 4 \text { if } x < 0 \ x \text { if } x \geq 0 \end{array} ; \right.$ Domain: $( - \infty , 0 ] \cup ( 4 )$, Range: $( - \infty , \infty )$ 
C) $f ( x ) = \left\{ \begin{array} { l l } 4 & \text { if } x \leq 0 \ - x & \text { if } x > 0 \end{array} ; \right.$ Domain: $( - \infty , \infty )$, Range: $( - \infty , 0 ) \cup \{ 4 \}$ 
D) $f ( x ) = \left\{ \begin{array} { l l } 4 & \text { if } x < 0 \ - x & \text { if } x \geq 0 \end{array} ; \right.$ Domain: $( - \infty , \infty )$, Range: $( - \infty , 0 ] \cup \{ 4 \}$

Give a Rule for the Piecewise-Defined Function f(x)={4 if x<0−4x if x≥0;f ( x ) = \left\{ \begin{array} { l l } 4 & \text { if } x < 0 \\ - 4 x & \text { if } x \geq 0 \end{array} ; \right.f(x)={4−4x​ if x<0 if x≥0​;

Give a Rule for the Piecewise-Defined Function $f ( x ) = \left\{ \begin{array} { l l } 4 & \text { if } x < 0 \\ - 4 x & \text { if } x \geq 0 \end{array} ; \right.$
