It is the latter.
i was just wondering which is correct:
a function f is defined on an interval I is contonuous if lim as x->c for f(x) is f(c) for all x in I or for all c in I.
i thought it should be the former but the book that im reading states that its the latter.
thanks for the clarification..but may i know why, if for this case, it is the latter then for this case:
a function f is cont at c if every seq of points x_n in I such that lim as n->infinity for x_n is c if the lim n->inifinity f(x_n) is f(c).
in this case, we are talking about x_n in I and not for all c in I.
i hope im making sense
