Definition
A function f(x) is contimuous at a point a if and only if the following three conditions are satisfied:
i S(a) is defined
L Jim f) exists
L Jim fx) - S(a)
A function is discontinuous at a point a if it fails to be continuous at a.
1. Determine which of the three above conditions are not met so that the functions below are
discontinuous at the given point. Note: it could be more than one of the conditions.
