Error in Quiz1 of Existence of Derivative video for Course1

There is an error in Quiz1 of ‘Existence of Derivative’ video for Course2 Week 1. Can you please check? Thank You.

Hi @EulerianKnight! Thanks for noting this issue.

The problem is now fixed.

Thanks,

y = x^(1/3) is also differentiable, there’s an error in the video.

If you are talking about when x=0, yes, the function is non-differentiable, but other than that, it is.
