the curve is y=x/(x+1). how many lines that are tangent to this curve pass through the point (1,3) and where do they touch the curve?

You should try to do some of this yourself so we know where exactly you need help. Do you know how to find derivatives? Tangent lines? The helpers here don't like to just give answers.
