  1. Feb 4, 2013 #1
    I need to sketch the curve (1/x2) - 1

    Is this correct?

    Excuse the untidiness this was drawn in paint. :S

    I know the y axis is an asymptote to the function, I haven't sketch a graph like this before so I'm kind of confused.

    when x=1 then what is y? do you see that point on your graph?

    similarly for x=-1

    try generating several points at x=2,3,4... and plot them
