I have a dilemma! I was taught that derivative function endpoints are not differentiable. However, what about in a case where the original function is fully differentiable but has a domain restriction? As the endpoints of the derivative function could be found if there were no domain on the original function, would I draw closed or open circles?

i borrowed out my TI-nspire CXII to someone who lost it. I still have the online Ti-nspire app on my laptop with all my saved documents and UDFs. Could I install everything I had in my entire calculator onto a new one if I bought one? This is an emergency, please help!
