Multiple Choice

Evaluate $f ( - 1 )$ , $f ( 0 )$ , $f ( 1 )$
, for the piecewise-defined function. $$f ( x ) = \left\{ \begin{array} { l l } 3 x ^ { 2 } & \text { if } x < 0 \\2 x + 1 & \text { if } x \geq 0\end{array} \right.$$

A) $f ( - 1 ) = 3$ , $f ( 0 ) = 1$ , $f ( 1 ) = 3$
B) $f ( - 1 ) = 0$ , $f ( 0 ) = 3$ , $f ( 1 ) = - 3$
C) $f ( - 1 ) = - 1$ , $f ( 0 ) = 0$ , $f ( 1 ) = 1$
D) $f ( - 1 ) = 3$ , $f ( 0 ) = 1$ , $f ( 1 ) = - 3$
E) none of these
