I've been stuck on this question on my homework for a while.
I know that for part (a) you need to use lim(f(x))=f(a) as x->a and for part (b) the limit definition of a derivative but I have no idea what to plug into either of the formulae.
For (a), f(x)=e^(-1/x) when x is not 0 and f(x)=p when x=0 so shouldn't the only value of p for which it is continuous be 0?
