Those friendly functions that don't contain breaks, bends or cusps are "differentiable". Take their derivative, or just infer some facts about them from the Mean Value Theorem.

Local Linear Approximation


If \(f(1)=4\) and \(f'(1)=6,\) which of the following is the best local linear approximation for \(f(1.01)?\)
