Assume Y is continuous on [c, d] and differentiable on (c,d). (a) If y is non-decreasing (monotone increasing) is it true that y'≥ 0? (Either prove your answer or give a counterexample). (b) If y is strictly increasing, is it true that y'> 0? Either give a counterexample and show where the proof of (a) fails or prove your statement.
