Observe the table:
\The table represents the temperatures at various depth.
\Hence, the ordered pairs are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=60cf07de955b9f9734184c0c9bfa9990.png\")

The change in temperature is not constant so one equation cannot be used to find any temperature value.

\Find relation is a function.
\Each depth is paired with only one temperature.
