    It is difficult to help because we don't know how the definitions or theorems work.
    How do your notes define jump? I have seen it defined exactly as what you are asked to prove.

    Have you proved that if f is increasing on open interval I then f(x-)~\&~f(x+) (the left-hand limit and the right-hand limit) exist for \forall x\in I~?

    If you have that theorem then apply it to this problem.

    If not, try to prove it. Or post the theorems and definitions you have to use.
