Question

How to prove a function is differentiable on an interval?

Answer 1

Answer:

, a differentiable function of one real variable is a function whose derivative exists at each point in its domain. As a result, the graph of a differentiable function must have a tangent line at each interior point in its domain, be relatively smooth, and cannot contain any breaks, bends, or cusps.
