Use the tables to evaluate the expression $(g \circ f)(3)$.
\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|}
\hline$x$ & 1 & 3 & & 6 & $x$ & 1 & 3 & & 6 \\
\hline$f(x)$ & 4 & 6 & 1 & 3 & $g(x)$ & 3 & & & 7 \\
\hline
\end{tabular}
\[
(g \circ f)(3)=\square
\]

Answer

Final Answer: $(g \circ f)(3)=\boxed{7}$

Steps

Step 1 ：The expression $(g \circ f)(3)$ represents the composition of two functions, $g$ and $f$.

Step 2 ：To evaluate this expression, we first find the value of $f(3)$ from the table, which is 6.

Step 3 ：We then substitute this value into $g(x)$, so we need to find the value of $g(6)$ from the table, which is 7.

Step 4 ：So, $(g \circ f)(3)=g(f(3))=g(6)=7$

Step 5 ：Final Answer: $(g \circ f)(3)=\boxed{7}$
