    Function Limit statments

    Good morning from Israel

    I'm a first year student learning about function limits.. I need to prove / disprove the following statements which I got a bit tangled up with..



    " Prove or disprove with a contradictory example "




    " If (limit*) exists, than there is a (delta > 0) so that to every (delta>|x|>0 ) exists (f(x)!=0) "

    Thanks
