Sir, I have a question for you. Does the derivative exist at a endpoint for a closed interval?

At 35:16 you say using a union is incorrect. What did you mean by there are lots of missing numbers. Both sections are decreasing so I'm not sure what you meant by "lots of missing numbers."

Number 9 is much easier if you use the quotient rule.

Do we also put V.As along with C.Ns and endpoints on the sign diagram? I’m trying to figure out why zero is on the sign diagram instead of just -14 alone

Hello! for the last question b) -1+14=13 not -13 so it would be decreasing not increasing?
