I am solving old comprehensive real analysis exams and there are two questions that I can not be sure,

  1. If $f$ is Riemann integrable then $|f|^r$ is Riemann integrable for any $r>0$.( True or False) I feel it is wrong indeed but couldnt find any example)

  2. $1, any function $f$ is in $L^q$ but not in $L^p$ and not in $L^r$.

Thank you for any help.

    I thought the same thing r should be between 1 and zero. I tried to use the theorem saying that if f is riemann integrable then the total measure of the jump points are zero, So I have to increase the measure of jump points.2012-12-16
