Find the value $x=$a where the function is discontinuous. For the point of discontinuity, give $($a$)f(a)$ if it exists, $($b$)\underset{x{a}^{-}}{lim}f(x),(c)\underset{x{a}^{+}}{lim}f(x),($d$)\underset{xa}{lim}f(x),$ and $(e)$ identify which conditions for continulty are not met.

$a=$

$($a$)$ Select the choice below and, if necessary, fill in the answer box within your choice.

A$.f(a)=$

B$.f(a)$ is undefined.

$($b$)$ Select the choice below and, if necessary, fill in the answer box within your choice.

A$.\underset{x{a}^{-}}{lim}f(x)=$

B$.\underset{x{a}^{-}}{lim}f(x)$ does not exist.
