Question

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