Hi. I was doing a practice exam, and came across this question: "What is the equation of this graph: http://img96.imageshack.us/img96/8089/untitled1copyhe1.jpg [Broken]"[/URL] If i am given a graph, and i dont know what type of graph it is, is there any way i can find an equation? The question also shows a vertical asymptote at at x=-1, and a horizontal asymptote at y=1. All help greatly appreciated. Thanks in advance, Dan.
