yeah i do believe it does mean that. However I don't know how to go about solving it then... if it were to mean that then for the first question: f(x)=3[x], a=-1, it would not exist because x E(is not) in the Z(intergers)? then for the second question where sinx=an interger that is...

hi, So i have a few questions and i can't seem to wrap my head around it. Q1 Decide which of the following functions has a removable discontinuity at a, and then if it is so..remove the discontinuity. f(x)=3[x]; a=-1. (I don't think there is a removable discontinuity because...
