Define x to be an limit point of a set s if every ball about x contains points of s other than x. (note that x need not lie in s
and that this definition of limit point may differ slightly from how the term was discussed informally in class.) if s is closed, show that it contains all of its limit points. for general s, prove that cl s is the union of s and all its limit points.
I would say rising education costs. most people can no longer afford to support another person especially with student debt taking a large portion of their income.
