HELLO EVERYONE!

If someone gets a chance, can you help assist me in a problem. I am just not getting it. It is for my intro to calculus class.

The problem is:

Find the open interval(s) where the function is changing as requested.

Increasing; y = Square root x^2 = 2

a. ( -1 , ∞ )
b. ( -∞ , 0 )
c. ( 0 , ∞ )
d. None

I dont know where to start or anything. ANy help would be gratly appreciate. I just need someone to help me start it and I can do the rest of the work.

Stapel, can you run a check on all these recent posts in the Calculus section, please? Starting from "Tysong" "Math Help" and going on up. Something very fishy is going on.

Thank you!

Yes, it's the same bunch as flooded the forum not so long ago.

Note to "all the students": Please stop flooding the forum in this manner, as this treatment of the volunteers is highly unlikely to garner the assistance you seek -- unless Soroban decides to do your homework for you.

In the future, please consider starting early to work on your homework, so you can find your problem spots near the beginning of the weekend, rather than "two hours" before the assignment is due. Also, by starting your work sooner than just before it's due, you'll have made progress sufficient to allow you to show your effort and take advantage of the hints and helps provided, instead of having to hope against hope that Soroban is around to rescue you in time.

Thank you.
