\begin{tabular}{|r|r|r|r|} \hlinexx & 4 & 6 & 11 \\ \hlineyy & 5 & 10 & 13 \\ \hline \end{tabular}
\begin{tabular}{|r|r|r|r|} \hlinexx & 4 & 6 & 6 \\ \hlineyy & 5 & 10 & 13 \\ \hline \end{tabular}
\begin{tabular}{|r|r|r|r|} \hlinexx & 4 & 6 & 11 \\ \hlineyy & 5 & 10 & 10 \\ \hline \end{tabular}

Studdy Solution
Check if the third table is one-to-one:
The y y value 10 is repeated for different x x values (6 and 11). Therefore, it is not one-to-one.
The tables that represent y y as a function of x x and are one-to-one are:
\begin{tabular}{|r|r|r|r|} \hline x & 4 & 6 & 11 \\ \hline y & 5 & 10 & 13 \\ \hline \end{tabular}
