  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with:
+close
  1. Feel free to nominate the person for helper of the week in #helper-nominations
  2. Do not ping the mods, unless someone is breaking the rules.
  3. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

and for the absolute value i think it's best that you just plot them

#

like 12.

atomic kayak
#

Is there a way i can solve it algebraically?

marsh osprey
marsh osprey
#

then solve it like you normally would for derivatives

What about for #29

#

Where f(b) doesnt equal f(a)

marsh osprey
atomic kayak
#

Yea

marsh osprey
atomic kayak
#

Like f(1) doesnt equal f(-1)

#

The answer was (0,0) for min and (-1?5) for max but i dont know how they for 0,0 without graphing

marsh osprey
#

so basically
f'(x) for that question is
2x^(-1/3) - 2 right?

atomic kayak
#

Just 2

#

Wait yes

marsh osprey
#

when f'(x) = 0
x = 0 is undefined

#

but x = 0 is in the domain

#

so it's one of the local extrema

atomic kayak
#

Oh

#

So

marsh osprey
#

you need to watch out when solving f'(x) = 0
to always look at domain of the function

atomic kayak
#

For questions like this i find f’(c) = 0 or undef?

marsh osprey
#

yeah but for undef it need to be in domain

atomic kayak
#

Ohh ok

#

Oh ty
