Given the following graph: http://img245.imageshack.us/img245/2395/scan0001ou4.gif How can i sketch the reciprocal of that function? There are poles at x=-2 and x=2, so it means its reciprocal will have roots at -2 and 2 right? But thats not really enough information to compose a full sketch. How should i go about doing this? Thanks, Dan.
