[pstricks] Graphs within list environment

[bereket T]

Hi Everyone:

I am trying to use PStricks graphs within a list
environment. However, I am not happy with they way it
looks. Particularly, the position of the numbering in
relation to the graphs. I wish also to put the graphs
side by side so that I can save some space. 

I have also the same problems with equations and
matrices in latex. Does someone have any idea on how
to go around this problem.

I have included an example.

Thanks very much.

\usepackage{pstricks,pst-plot,pstricks-add}

%Axes sytle settings
\newpsstyle{plainAxes}{arrows=->,ticks=none}

-3pt,labels=none}
\newpsstyle{labeledAxes}{arrows=->,ticksize=2pt
-2pt,labelsep=2.5pt,labelFontSize=\footnotesize}

%Plot style setting

Which of the following graphs represent the graph of a
function.
\begin{enumerate}
\item 
\begin{psgraph*}[style=plainAxes,xAxisLabel=\textit{x}](0,0)(-2.5,-2.5)(2.5,2.5){5cm}{!}
\psplot[style=algeline]{-2.5}{2.5}{x + 1}
\end{psgraph*}

\item 
\begin{psgraph*}[style=plainAxes,xAxisLabel=\textit{x}](0,0)(-2.5,-2.5)(2.5,2.5){5cm}{!}
\psplot[style=algeline,swapaxes=true]{-2.5}{2.5}{x^2-1}
\end{psgraph*}

\item 
\begin{psgraph*}[style=plainAxes,xAxisLabel=\textit{x}](0,0)(-2.5,-2.5)(2.5,2.5){5cm}{!}
\psplot[style=algeline]{-2.5}{2.5}{x^3}
\end{psgraph*}

\item 
\begin{psgraph*}[style=plainAxes,xAxisLabel=\textit{x}](0,0)(-2.5,-2.5)(2.5,2.5){5cm}{!}
\psplot[style=algeline]{-2.5}{2.5}{abs(x)}
