Let $\displaystyle{f(x) = \begin{cases} -3x, & x < 5, \\ 1, & x = 5,\\ 3x, & x > 5. \end{cases} }$, Find the indicated one-sided limits of $f(x)$, and determine the continuity of $f(x)$ at the indicated point. You may sketch a graph of $y=f(x)$, including hollow and solid circles in the appropriate places. NOTE: Type DNE if a limit does not exist. $\displaystyle{\lim_{x \rightarrow 5^{-}} f(x) }$ = . $\displaystyle{\lim_{x \rightarrow 5^{+}} f(x) }$= . $\displaystyle{\lim_{x \rightarrow 5} f(x) }$= . $\displaystyle{ f(5) }$= . Is $f(x)$ continuous at $x=5$? (Yes/No) .
