I want to plot two equations on a line graph, (prices depending on costs), no luck anything I try: P1 = C1 + a*P2 P2 = C1 +b*P1 Can you help?

How about

  f[x_] := x
  g[x_] := x^2
  a[x_] := Piecewise[{{x^3, x < 0}, {1/x, x > 0}}]
  b[x_] := Piecewise[{{Sin[10*x]/x, x < 0}, {1, x == 0}}, Cos[10*x]]

  Show[{Plot[f[x], {x, 1, 2}, PlotStyle -> Blue], Plot[g[x], {x, -2, -1}, PlotStyle -> Green]}, PlotRange -> All,
  AxesOrigin -> {0, 0}]

enter image description here

Or more complex.

   Show[{Plot[f[x], {x, 1/2, 2}, PlotStyle -> Orange], 
   Plot[g[x], {x, -2, -1/2}, PlotStyle -> Blue], 
   Plot[a[x], {x, -1, 1}, PlotStyle -> Red], 
   Plot[b[x], {x, -2, 2}, PlotStyle -> Black]}, PlotRange -> All, 
   AxesOrigin -> {0, 0}]

Yes, thank you that helped a lot! However, I've put 5 functions into the graph now, and each time I go to put in the 6th a message pops up that says it "can't combine the graphic objects in show". I tried putting in different functions to see if it was only because my syntax was incorrect, but the same message comes up each time.

I can't help if you don't put a example code.What have you done?. :)
