This isn't a homework question, although I am in a calculus course. I'm a little fuzzy on the method that I was taught (discover intervals and all that nonsense to make(adsbygoogle = window.adsbygoogle || []).push({}); suref'(x)=0 is a max or a min). I was curious if, when I discovered the values of x such f'(x)=0, I could then find f''(x)=0 to determine if each f'(x) is a max/min, or merely a concavity point (thus, if f''(x)=0 is the same as f'(x)=0, it isn't a max/min).

Thanks!
