    Integration problem

    Calculate the area bounded by the graphs of f(x)=x^2, g(x)=x^-2, x>0 and the line x=3 I keep getting 25/3 u^2 but the book says it is 8u^2. Can someone please clarify it for me? Thanks

    Further Graphs

    MIF's (yes i know) explanation is kind of weird but in any case, I don't get it. Sketch x^2/(x^2)-9 I don't know how to find the vertical asymptotes. I think it would be best if you could kindly write out every step for better clarification. Thanks :DDDDD
