1. The problem statement, all variables and given/known data Sketch the graph of (x-1)/(1-x^2). 2. Relevant equations Vertical Asymptotes are found in the denominator. 3. The attempt at a solution I have all I need to sketch this graph except the vertical asymptote. The 1-x^2 is throwing me off. I thought it would come out as a difference of squares, but this can also be -x^2+1.
