comment Why is the second derivative test inconclusive for some local max/mins?
@Amzoti Thats not what I am looking for. Sorry maybe I am poorly wording my question. I know those graphs prove my above answers. However, I want to know why logically $f''(0)$ should be $0$ not negative. For instance, I know $f'(0)=0$ because we have a horizontal tangent there. I want a similar explanation for why $f''(0)$ is $0$ not negative.

Yeah this was ridiculously easy. As I said it had been a while since I have done DEs so I had a brain freeze.

It is missing the squared in the solution which I have fixed
