What is an example of when it is undefined and in the domain?

@moonira0209 the domain of the function... videos on that too : )

What does he mean by domain? Wats the domain here?
patrickJMT (November 30, 1999 at 12:00 am)
@iixsarah the values also have to be in the domain of the original function. this is the part no one remembers!

@vindrila ha : )

I should make "Thank you" auto comment for your videos ;)

@iixsarah the derivative f '(x) needs to be undefined but if you plug 3 and -3 into the original equation f(x) it's also undefined which means it doesn't exist on the graph... at least that's how I understand it.

@brittnibeers you should read the definition a bit closer for critical numbers.
brittnibeers (November 30, 1999 at 12:00 am)
I DON'T UNDERSTAND WHY ISN'T 3 AND -3 ACCEPTED. Critical numbers are defined as f'(x)=undefined so why why WHYYY ;A;
iixsarah (November 30, 1999 at 12:00 am)
but arent critical numbers x-values such that f'(x)=0 and/or f'(x)=undefined? so why can't -3 and 3 work? if you plug it into the derivative, it's undefined.. |
