Actually if f '' (x) = 0 you don't know what it is and have to use a sign chart. I could be a min, max, or inflection. example y= x^4.

I appreciate the videos but you seem to almost always show the conventional cookie cutter problem... But I think a lot of the time people like me come on here to find a video explaining how to solve a problem that is unlike the basic, cookie cutter problem because nobody else will show them. My question is... how would you solve something like y=x^4-6x^2 because at a point... you will not be able to factor and that confuses me as to where to go from after that point?

Sal, you are so popular! Your phone always rings during your videos.
-
At least "concativity" sounds like a real word. :P
Also, this is so fun. hahah.
-
You keep pronouncing "concavity" wrong !!!!!!
-
wow the phone is ringing!....probably the telemarketer?
-
thankyou so much...
-
awesome!!! :)

concativity lol...
