Analysis Help

    I really need help on this. Completely lost. Please help me.
    Let f: [a,b] -> R. Given f is integrable and bounded below, show 1/f is integrable.

    It's not true. What about f(x)=x on [0,1]?

    Well, perhaps he meant that 0<|f|<k, on [0,1] for some constant k?

    We can't because we have shown the question to be false.

    It would help if you would state exactly what the problem is. It cannot be what you originally wrote!
