Question

Function $f$ is $f ( x ) = \left\{ \begin{array} { c l } 
- 2 & \text { if } 0 \leq x < 14 \
- 3 x & \text { if } 14 \leq x < 28
\end{array} \right.$ .   
Find $f ( 27 )$ .
 
A)2
B) -81
C) -83
D) -2
E) 28

Quizplus · Accepted Answer

For $x = 27$, the condition $14 \leq x < 28$ applies, so we use the formula $f(x) = -3x$. Substituting $x = 27$ gives $f(27) = -3(27) = -81$.
