Which set represents the same relation as the table below?

\begin{tabular}{|c|c|}
\hline
[tex]$x$[/tex] & [tex]$f(x)$[/tex] \\
\hline
0 & 5 \\
\hline
4 & 2 \\
\hline
6 & 9 \\
\hline
9 & 10 \\
\hline
\end{tabular}

A. [tex]$\{(0,5),(4,2),(6,9),(9,10)\}$[/tex]

B. [tex]$\{(5,0),(2,4),(9,6),(10,9)\}$[/tex]

C. [tex]$\{0,2,4,5,6,9,10\}$[/tex]

D. [tex]$\{2,5,9,10\}$[/tex]


Sagot :

To determine which set represents the same relation as the table, we need to compare each option with the given table. The table shows the relationship between [tex]\( x \)[/tex] and [tex]\( f(x) \)[/tex]. The table is as follows:

[tex]\[ \begin{array}{|c|c|} \hline x & f(x) \\ \hline 0 & 5 \\ \hline 4 & 2 \\ \hline 6 & 9 \\ \hline 9 & 10 \\ \hline \end{array} \][/tex]

We need to find a set that matches this relationship.

### Option Analysis

1. Option 1: { (0, 5), (4, 2), (6, 9), (9, 10) }

This set directly consists of the ordered pairs from the table:
- (0, 5)
- (4, 2)
- (6, 9)
- (9, 10)

This matches the table perfectly.

2. Option 2: { (5, 0), (2, 4), (9, 6), (10, 9) }

This set consists of the reverse of the ordered pairs:
- (5, 0) instead of (0, 5)
- (2, 4) instead of (4, 2)
- (9, 6) instead of (6, 9)
- (10, 9) instead of (9, 10)

This does not match the table.

3. Option 3: { 0, 2, 4, 5, 6, 9, 10 }

This set lists individual elements but does not present them as ordered pairs, so it does not represent a relation.

This does not match the table.

4. Option 4: { 2, 5, 9, 10 }

This set includes some of the values from [tex]\( f(x) \)[/tex] but none of the corresponding [tex]\( x \)[/tex] values, and it does not present them as ordered pairs.

This does not match the table.

### Conclusion

The set that represents the same relation as the table is:

[tex]\[ \{(0,5),(4,2),(6,9),(9,10)\} \][/tex]

This directly corresponds to Option 1, which matches the given table exactly.
