Find all values $x=$a where the function is discontinuous. For each point of discontinuity, give $($a$)\underset{?}{lim}f(x),($b$)\underset{?}{lim}f(x),(c)\underset{?}{lim}f(x),($d$)f(a)$ If it exists, and $($e$)$ identify which conditions for continuity are not met. Be sure to $x{a}^{}x$a note when the limit doesn't exist.

$f(x)$ is discontinuous at $x=$
