Complete the following table for $f(x)=\frac{x^2}{x-6},$ then estimate the limit and describe the behavior of the function as $x$ approaches $6.$

Round your answers in the table to the nearest integer.

$\backslash$table$[[x,5\mathrm{.}9,5\mathrm{.}99,5\mathrm{.}999,6,6\mathrm{.}001,6\mathrm{.}01,6\mathrm{.}1],[f(x),,,,$Undefined,,,$]]$

Round your answer for the limit to two decimal places.

If the limit does not exist, enter DNE.

$\underset{x6}{lim}(\frac{x^2}{x-6})=$
