Question

Function $f$ is $f ( x ) = \left\{ \begin{array} { c l } 
4 x & \text { if } 0 < x < 16 \
x + 3 & \text { if } 16 \leq x < 32 \
4 x & \text { if } 32 \leq x \leq 48
\end{array} \right.$ . 
Find $f ( 38 )$ .

A)152
B) 156
C) 48
D) 38
E) 168

Quizplus · Accepted Answer

Since $38$ falls in the range $32 \leq x \leq 48$, we use the function $f(x) = 4x$. Thus, $f(38) = 4 \times 38 = 152$.
