Explanation
We are given the following:
We are required to determine the following:
[tex]\begin{gathered} (a)\text{ }\lim_{x\to-4^-}f(x) \\ (b)\text{ }\lim_{x\to-2^}f(x) \\ (c)\text{ }f(-2) \\ (d)\text{ }\lim_{x\to-1^+}f(x) \end{gathered}[/tex]
This can be achieved thus:
(a)
[tex]\lim_{x\to-4^-}f(x)=-1[/tex]
(b)
[tex]\lim_{x\to-2}f(x)=-3\text{ \textbraceleft either from the left or right\textbraceright}[/tex]
(c)
[tex][/tex]
