B) $f ( x ) = \left\{ \begin{array} { l l } 4 , & \text { for } x < - 1 \\x ^ { 2 } - 1 , & \text { for } x \geq - 1\end{array} \right.$
C) $f ( x ) = \left\{ \begin{array} { l l } 4 , & \text { for } x < - 1 \\x ^ { 3 } - 1 , & \text { for } x \geq - 1\end{array} \right.$
D) $f ( x ) = \left\{ \begin{array} { l l } 4 , & \text { for } x < - 1 \\x ^ { 2 } , & \text { for } x \geq - 1\end{array} \right.$
