Write an Equation for the Piecewise Function $f ( x ) = \left\{ \begin{array} { l l } x - 3 , & \text { for } x \leq 0 \\- x ^ { 2 } , & \text { for } x > 0\end{array} \right.$

-

• A) \(f ( x ) = \left\{ \begin{array} { l l } x - 3 , & \text { for } x \leq 0 \\ - x ^ { 2 } , & \text { for } x > 0 \end{array} \right.\)
• B) \(f ( x ) = \left\{ \begin{array} { l l } x + 3 , & \text { for } x \leq 0 \\ \sqrt { x } , & \text { for } x > 0 \end{array} \right.\)
• C) \(f ( x ) = \left\{ \begin{array} { l l } x + 3 , & \text { for } x \leq 0 \\ - \sqrt { x } , & \text { for } x > 0 \end{array} \right.\)
• D) \(f ( x ) = \left\{ \begin{array} { l l } - x + 3 , & \text { for } x \leq 0 \\ - \sqrt { x } , & \text { for } x > 0 \end{array} \right.\)
