Find $\underset{x10}{lim}f(x)$ using the table shown below. Be sure to fill out the table and round all numbers to three decimal places.

$f(x)=\frac{x-10}{\sqrt[\phantom{2}]{x}-\sqrt[\phantom{2}]{10}}$

$\backslash$table$[[x,9\mathrm{.}9,9\mathrm{.}99,9\mathrm{.}999,10,10\mathrm{.}001,10\mathrm{.}01,10\mathrm{.}1],[f(x),,,,,x,,]]$
