Sagot :
To determine the value of [tex]\( f(5) \)[/tex], we need to refer to the provided table, which defines the values of the function [tex]\( f \)[/tex] for specific inputs [tex]\( x \)[/tex]. The table is as follows:
[tex]\[ \begin{array}{|c|c|} \hline x & f(x) \\ \hline -4 & -2 \\ \hline -1 & 5 \\ \hline 3 & 4 \\ \hline 5 & -8 \\ \hline \end{array} \][/tex]
From the table, we can see the following pairs [tex]\((x, f(x))\)[/tex]:
- When [tex]\( x = -4 \)[/tex], [tex]\( f(x) = -2 \)[/tex]
- When [tex]\( x = -1 \)[/tex], [tex]\( f(x) = 5 \)[/tex]
- When [tex]\( x = 3 \)[/tex], [tex]\( f(x) = 4 \)[/tex]
- When [tex]\( x = 5 \)[/tex], [tex]\( f(x) = -8 \)[/tex]
To find [tex]\( f(5) \)[/tex], we look for the row where [tex]\( x = 5 \)[/tex]. According to the table:
[tex]\[ x = 5 \implies f(5) = -8 \][/tex]
Thus, the value of [tex]\( f(5) \)[/tex] is [tex]\(-8\)[/tex].
Therefore, the correct answer is:
[tex]\[ \boxed{-8} \][/tex]
[tex]\[ \begin{array}{|c|c|} \hline x & f(x) \\ \hline -4 & -2 \\ \hline -1 & 5 \\ \hline 3 & 4 \\ \hline 5 & -8 \\ \hline \end{array} \][/tex]
From the table, we can see the following pairs [tex]\((x, f(x))\)[/tex]:
- When [tex]\( x = -4 \)[/tex], [tex]\( f(x) = -2 \)[/tex]
- When [tex]\( x = -1 \)[/tex], [tex]\( f(x) = 5 \)[/tex]
- When [tex]\( x = 3 \)[/tex], [tex]\( f(x) = 4 \)[/tex]
- When [tex]\( x = 5 \)[/tex], [tex]\( f(x) = -8 \)[/tex]
To find [tex]\( f(5) \)[/tex], we look for the row where [tex]\( x = 5 \)[/tex]. According to the table:
[tex]\[ x = 5 \implies f(5) = -8 \][/tex]
Thus, the value of [tex]\( f(5) \)[/tex] is [tex]\(-8\)[/tex].
Therefore, the correct answer is:
[tex]\[ \boxed{-8} \][/tex]
