2. Either prove the assertion or show that the assertion is not valid by giving a counterexample. A pictorial counterexample is sufficient. (a) If f increases on [a, b] and increases on [b, c], then f increases on [a, c). (b) If f increases on [a, b] and increases on (b, c), then f increases on [a, c).
