12.1 Exercise 28

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

$\underset{x \rightarrow - 3}{\lim} f \left(x\right) = 2$, $\underset{x \rightarrow 1^{+}}{\lim} f \left(x\right) = - 2$, $\underset{x \rightarrow 3}{\lim} f \left(x\right) = – 4$, $f \left(– 3\right) = 0$, $f \left(0\right) = 0$
