Let $f$ be the function holnws Vnu nan click on the graph to get a larger image.

Determine the limits for the function $f$ at $1.$ Note that the limits are all integers $($e$.$g$.$

cdots,$-2,-1,0,1,2,$cdots

$\underset{x{1}^{-}}{lim}f(x)=$

$$

$f(1)=$

$\underset{x{1}^{+}}{lim}f(x)=$

$$

Is this function continuous at $1?$

$($yes$/$no$)$:

Can one change the value of this function at $1$ to some value other than its current value, and make the function continuous at $1?$

$($yes$/$no$)$:
