This image illustrates $\underset{x8}{lim}f(x)=2.$ The red lines are $x=8$ and $y=2.$ The horizontal, dashed, green lines are a distance of $=0\mathrm{.}2$ above and below the limit$.$ The vertical, dashed, green lines are at the intersections of the curve with the horizontal lines.

For this value of $,$ which of the following values is the most likely to be $?$

$2\mathrm{.}168$

$2\mathrm{.}648$
