The Graph of a Piecewise-Defined Function Is Given B) C)

The graph of a piecewise-defined function is given. Write a definition for the function.

A)
$f ( x ) = \left\{ \begin{array} { l l } \frac { 3 } { 4 } x + 4 & \text { if } - 3 \leq x \leq 0 \\ \frac { 3 } { 2 } x & \text { if } x \geq 0 \end{array} \right.$
B)
$f ( x ) = \left\{ \begin{array} { l l } \frac { 3 } { 4 } x + 4 & \text { if } - 3 \leq x \leq 0 \\ \frac { 3 } { 2 } x & \text { if } x > 0 \end{array} \right.$
C)
$$f ( x ) = \left\{ \begin{array} { l l } \frac { 4 } { 3 } x + 4 & \text { if } - 3 \leq x \leq 0 \\\frac { 2 } { 3 } x & \text { if } 0 < x \leq 3\end{array}D) \ f ( x ) = \left\{ \begin{array} { l l } \frac { 4 } { 3 } x + 4 & \text { if } - 3 \leq x \leq 0 \\\frac { 2 } { 3 } x & \text { if } x > 0\end{array} \right. \right.$$
