You need to give m + Q a new name.

Otherwise when you do (m + Q).set_axes_range(...) that gets applied to an object which you can no longer recover.

And when you later do (m + Q).get_axes_range(...) you are computing m + Q again and that cannot know about the operation you did on the lost object.

Try this:

sage: mQ = m+Q
sage: mQ.set_axes_range(xmin=-0.2,xmax=5.5,ymin=-0.5,ymax=1)
sage: print(mQ.get_axes_range())
sage: mQ.show()
