12.1 Exercise 23

Draw the graph of a function from the functional values and limits provided.

$\underset{x \rightarrow 0^{-}}{\lim} f \left(x\right) = 2$, $\underset{x \rightarrow 0^{+}}{\lim} f \left(x\right) = – 3$, $\underset{x \rightarrow 2}{\lim} f \left(x\right) = 2$, $f \left(0\right) = 4$, $f \left(2\right) = – 1$, $f \left(– 3\right) \textrm{ }\text{does}\textrm{ }\text{not}\textrm{ }\text{exist} .$
