\begin{document}
\psset{xunit=2cm,yunit=2cm}
\begin{pspicture}(-2.25,-1.25)(2.5,1.5)%\psgrid
  \psaxes[Dx=0.5,Dy=0.5]{->}(0,0)(-2.1,-1.1)(2.5,1.5)
  \uput[45](2.5,0){$x$}
  \uput[90](0,1.5){$g(x)$}
  \psline[linewidth=2pt](-0.05,-1)(0,-1)(0,1)(1,1)(1,-1)(2,-1)(2,1)(2.05,1)
  \psplot[linecolor=red,plotpoints=400,linewidth=.5pt]{-2.25}{2.25}{180
