\hline
0 & 0 \\

Sagot :

To determine the value of [tex]\( f(3) \)[/tex] using the given table, we simply need to find the value in the table where [tex]\( x = 3 \)[/tex].

Here’s the table again for reference:
[tex]\[ \begin{array}{|c|c|} \hline x & f(x) \\ \hline -3 & -9 \\ \hline -2 & -6 \\ \hline -1 & -3 \\ \hline 0 & 0 \\ \hline 1 & 3 \\ \hline 2 & 6 \\ \hline 3 & 9 \\ \hline \end{array} \][/tex]

From the table, locate the row corresponding to [tex]\( x = 3 \)[/tex]:

[tex]\[ \begin{array}{|c|c|} \hline x & f(x) \\ \hline 3 & 9 \\ \hline \end{array} \][/tex]

Reading off the table, we see that when [tex]\( x = 3 \)[/tex], [tex]\( f(x) = 9 \)[/tex].

Therefore, [tex]\( f(3) = 9 \)[/tex].

The correct answer is [tex]\( 9 \)[/tex].
