How to Find the Domain of Any Function (NancyPi)

[@YTRMoney]

this... this... this is talent... writing backwords??? this girl deserves a noble peace prize

[@icuppu2]

She should have a spelling video, too, and maybe she just might win a Nobel prize.

[@aidaaqilahmohdzin5542]

Hahah. Actually i do think she recorded a selfie video. So,she wrote normally like us hehhe

[@Miss__Victoria]

actually anyone can write backwards with their non dominant hand. take a pencil in both hands and on two different pieces of paper or a whiteboard look straight ahead and try to write the same exact word with both hands. dont think about how, dont look at either hand. just write and look straight forward. its a mind trick I figured out in middle school. your dominant hand will be normal and the non dominant will be a mirror image. the left and right hemispheres of the brain control opposites sides of the body and can mirror each others movements if you just dont interfere by thinking about it. It freaks people out lol.

[@rhysand6629]

Can we all just take a second to appreciate that not only is she doing a great job teaching math, but she is doing it while writing it backwards from her perspective.

[@tobysmailes2064]

I recon she writes forward (for her) and then flips the video. Bottom line is we only know her backwards.

[@Etk333]

She's not writing backwards dude lol

[@mrlegible4894]

On the square root only section you have X^2 + 5X + 6. That factors into (X +3)(X + 2). Now you only flip an inequality sign when you divide or multiply by a negative number, which this problem doesn't require. So you end up with: X >= -3 or X >= -2. So I don't understand how you got X

[@alfredpeter2404]

Same here, been trying to figure this out for a while now!

[@mazharabbasbukhari7390]

i am also confuse at this same point,but i assume as one factor as positive and one as negative.lol

[@tamachanusko]

x cant be more than -3. -2.5, -2.6, -2,7 etc will break the >= 0.

[@feero9680]

There is nothing wrong with her working. She mentioned, that is a quadratic inequality, which means there is a slightly different method of solving that eqn. In quadratic inequality, u find x like normal quadratic. And then with that x, u find the critical region. Remember b^2-2ac ? Thats how she ends up with that As she said, check out her other video on that. Sry bad english tho

What if you have a cubed root on the bottom? Like if it's 1/ x³+x

[@MathEd-k3b]

Set the radicand > 0 and solve. So x(x^2 + 1) > 0, critical value is only 0 since x^2 + 1 is always positive. So x > 0 is domain.
