sebastian used the table and correctly identified that the data does not represent a logarithmic function.

\begin{array}{|c|c|}
\hline
x & y \\
\hline
1 & -5 \\
\hline
2 & 0 \\
\hline
4 & 4 \\
\hline
5 & 0 \\
\hline
6 & -5 \\
\hline
\end{array}

what information did sebastian use in his deduction?

- the table does not show a vertical asymptote.
- the table shows two $y$-intercepts and it changes from increasing to decreasing.
- the table shows one $x$-intercept and one $y$-intercept.
- the table shows two $x$-intercepts and it changes from increasing to decreasing.
