    Question has been attached

     y = 4 + \frac{1}{x} We know the graph crosses the x-axis at y = 0 so:

     x = -\frac{1}{4}

    When x = 0 then 1/x tends to infinity and thus y tends to infinity, so x = 0 is an asymptote.

    p = -\frac{1}{4}, q = 0

    http://www.wolframalpha.com/input/?i=y%3D+1%2Fx%2B4 that's the graph.

    Never heard of the trapezium rule but you could just integrate it
