-$f ( x ) = \left\{ \begin{array} { l r } - 3 x - 1 & \text { if } x

Question

Evaluate the piecewise function at the given value of the independent variable.
-$f ( x ) = \left\{ \begin{array} { l r } - 3 x - 1 & \text { if } x < 0 \ - 4 x - 2 & \text { if } x \geq 0 \end{array} ; f ( 3 ) \right.$
A) $- 14$
B) $- 11$
C) $- 13$
D) $- 15$

Since $x = 3$ is greater than 0, we use the second part of the piecewise function: $-4x - 2$. Substituting $x = 3$, we get $-4(3) - 2 = -12 - 2 = -14$.
