$1-$Sketch the graph of a function with the following properties:

$,f(2)=3,f(0)=0$

ii$.\underset{x2}{lim}f(x)=-1$

iii. $,f(x)$ is increasing when $\underset{x-1^{-}}{lim}f(x)=,\underset{x-1^{+}}{lim}f(x)=-x,\underset{x-}{lim}f(x)=1x=-12$

$x.\underset{x-1^{-}}{lim}f(x)=,\underset{x-1^{+}}{lim}f(x)=-$

$x,\underset{x-}{lim}f(x)=1$

$v.f$ has discontimuities only yor $x=-1$ and $2$
