Basically you want to save the picture, not show it. combining show and save is the problem. Try this:

a = plot(f1, (x,-1,2))
b = plot(f2, (x,-1,2))
c = plot(f3, (x,-1,2))
pic = a+b+c'pic.pdf')

Press on the link pic.pdf to see it and download it. Note, with multiple plots you might want to color them. This can be done, for example, with b = plot(f2, (x,-1,2),color='red'). If you want to show as well insert the line right after pic is defined.

EDIT: As Juanjo comments below, you can combine the 3 plots into 1. If you stack the functions together on one line using ; you can compress the code even more:

f1=x; f2=cos(x); f3=x^2
pic = plot([f1,f2,f3], (x,-1,2), color=["red","green", "blue"])'pic.pdf')

You can also combine the graphs with just one plot command:

pic = plot([f1,f2,f3], (x,-1,2), color=["red","green", "blue"])
