Question
**Find the requested value.**

Using the given tables, find \( (f \circ g)(2) \).

\[
\begin{array}{c|cccc}
x & 9 & 5 & 1 & 3 \\
\hline
f(x) & 18 & 10 & 2 & 6 \\
\end{array}
\]

\[
\begin{array}{c|cccc}
x & 4 & 2 & 5 & 3 \\
\hline
g(x) & 7 & 3 & 9 & 5 \\
\end{array}
\]

A) 6

B) 10

C) 3

D) 2

**Explanation:**

To find \( (f \circ g)(2) \), first determine \( g(2) \) from the second table. Here, when \( x = 2 \), \( g(x) = 3 \).

Next, find \( f(g(2)) = f(3) \) using the first table. For \( x = 3 \), \( f(x) = 6 \).

Hence, \( (f \circ g)(2) = 6 \). The correct answer is A) 6.
