Hi guys, so I'm having trouble with the following question:

http://img855.imageshack.us/img855/9...mttulo1wrl.png

For f'(x), I got 2x and for f"(x) I got 2...

I need the values for which f"(x)=0, but how can I find it then f"(x)=2? I couldn't find any similar examples on Google guys, please help.

Thanks i advance.

Cheers
