If $\lim _{x \rightarrow 0^{+}} f(x)=-2, \lim _{x \rightarrow 0^{-}} f(x)=3,$ and $f(0)=-2,$ what can you say about $\lim _{x \rightarrow 0} f(x) ?$
Limits
An Intuitive Introduction to Limits
$$ \begin{array}{l} \text { If } \lim _{x \rightarrow 0^{+}} f(x)=-2, \lim _{x \rightarrow 0^{-}} f(x)=3, \text { and } f(0)=-2, \text { what can }\\ \text { you say about } \lim _{x \rightarrow 0} f(x) \text { ? } \end{array} $$
$\begin{array}{ll}\lim _{x \rightarrow 2} f(x)=-\infty & \lim _{x \rightarrow \infty} f(x)=\infty, \quad \lim _{x \rightarrow-\infty} f(x)=0 \\ \lim _{x \rightarrow 0^{+}} f(x)=\infty, & \lim _{x \rightarrow 0^{-}} f(x)=-\infty\end{array}$
