thanks but how do i sketch the second one

Hi im just a beginner at 4u and im having trouble with curve sketching. Can someone sketch y=(x^2)/ (x^2-1) and then sketch (x^2-4x+4)/(x^2-4x+3)? Also can i have like a detailed working out of it? Its a case of f(x) into f(x-a) but idk what the a is. Thanks everyone.
