Consider the Definition of Continuity, and look at each graph & explain why the function is/is not continuous at r.

Please give explanation.

1. f(a) exists (i.e. the value of f(a) is finite) 2. Limy-a f(x) exists (i.e. the right-hand limit = left-hand limit, and both are finite) 3. Limx-a f(x) = f(a)
