May I plz get some assistance on the following question;

If f and g are integrable on a closed set and f(x)<=h(x)<=g(x) for all x in in that set then h (a function) is integrable on that set.

The statement is false.

Take and on the interval and if and 0 other wise. This shows that the statement is false for the Riemann integral.

For Lebesgue integrable take on a set and is not Lebesgue measurable, and 0 else where. Then is not Lebesgue integrable.
