volunteer	One at -1 over 9, so we're right on that.	21,191	492	[]
volunteer	Mm	21,191	493	[]
volunteer	So let's try 9 X minus.	21,191	494	[]
volunteer	E. Where's my square root?	21,191	495	[]
volunteer	X	21,191	496	[]
volunteer	-1.	21,191	497	[]
volunteer	There it is.	21,191	498	[]
volunteer	Because of the square root,	21,191	499	[]
volunteer	Um, the function doesn't exist.	21,191	500	[]
volunteer	Uh	21,191	501	[]
volunteer	When X is less than 0.	21,191	502	[]
volunteer	I knew something was different.	21,191	503	[]
volunteer	Even veers off differently, look at that behavior.	21,191	504	[]
volunteer	Wow.	21,191	505	[]
volunteer	OK.	21,191	506	[]
volunteer	As a as a smaller	21,191	507	[]
volunteer	Um, slope doesn't explode. It's not as narrow, it's wider.	21,191	508	[]
volunteer	we consider 1/81 as complex root.	21,191	509	[]
volunteer	I want to say yes.	21,191	510	[]
volunteer	I feel like part of me wants to say yes.	21,191	511	[]
student	because it exist as a root but does't satisfy the equation	21,191	512	[]
volunteer	I feel like this left hand side.	21,191	513	[]
volunteer	Because it exists as x < 0 doesn't satisfy the equation. Yeah, I feel like the when X is less than 0.	21,191	514	[]
volunteer	Um	21,191	515	[]
volunteer	It only exists in the complex plane.	21,191	516	[]
volunteer	Because we would by definition include I.	21,191	517	[]
volunteer	Because we have that square root of X.	21,191	518	[]
volunteer	So when Xs say,	21,191	519	[]
volunteer	equal to -1.	21,191	520	[]
volunteer	You'd have	21,191	521	[]
volunteer	9 times -1 to be -9 minus 8 times I.	21,191	522	[]
volunteer	-1	21,191	523	[]
volunteer	So you have like -10.	21,191	524	[]
volunteer	Minus 8 I.	21,191	525	[]
volunteer	Yeah, I think this does only have one real root, which is an integer.	21,191	526	[]
student	yeah	21,191	527	[]
volunteer	It is B	21,191	528	[]
volunteer	Man, this is annoying. Why can I not understand this unless I grafted it.	21,191	529	[]
volunteer	A square root threw me off.	21,191	530	[]
volunteer	Oh, and the behavior is different because	21,191	531	[]
volunteer	It's a line. It's supposed to be a line.	21,191	532	[]
volunteer	Because 9 X.	21,191	533	[]
volunteer	It's supposed to be alive, but the square root behavior.	21,191	534	[]
volunteer	try value. If X is equal to 0.5.	21,191	535	[]
volunteer	Let's say 0.25.	21,191	536	[]
volunteer	Then you have	21,191	537	[]
volunteer	9 times 0.25, which is 1.5. No.	21,191	538	[]
volunteer	It	21,191	539	[]
volunteer	2.25.	21,191	540	[]
volunteer	Minus	21,191	541	[]
volunteer	8 times 0.5, which is 4. OK, so that is negative.	21,191	542	[]
volunteer	Hm	21,191	543	[]
volunteer	That's so weird, that a square root can override a line.	21,191	544	[]
volunteer	So much	21,191	545	[]
volunteer	To dictate his behavior like this.	21,191	546	[]
volunteer	It's basically linear.	21,191	547	[]
volunteer	Yeah, with a climb of 15 to 80.	21,191	548	[]
volunteer	16/1.	21,191	549	[]
student	is it necessary when x < 0, it goes in complex plain? becuz there are so many instance when w and it satisfy the equation too	21,191	550	[]
volunteer	Yeah, it's pretty consistent climb.	21,191	551	[]
volunteer	Once we get past a certain point, it just becomes a line. I think once we get past one.	21,191	552	[]
volunteer	It just becomes alive. Is it this?	21,191	553	[]
volunteer	This is annoying. I can't hear when you	21,191	554	[]
volunteer	Type in the chat, it should notify me with like a noise, but I don't get it. I keep	21,191	555	[]
volunteer	Missing when you type in.	21,191	556	[]
volunteer	Do you mean when X is less than 0?	21,191	557	[]
student	yeah	21,191	558	[]
volunteer	Not when X is greater than 0.	21,191	559	[]
volunteer	OK.	21,191	560	[]
volunteer	I mean	21,191	561	[]
student	x < 0	21,191	562	[]
volunteer	Yeah, I mean that by like by definition, unless you had um the square root of the absolute value.	21,191	563	[]
volunteer	Then you, we would have, um,	21,191	564	[]
volunteer	Then we'll be able to define it when X is less than 0.	21,191	565	[]
volunteer	But as soon as we	21,191	566	[]
volunteer	But as soon as we try to go,	21,191	567	[]
volunteer	With a negative X, it immediately turns complex.	21,191	568	[]
student	how does it immediatey turn complex at -x?	21,191	569	[]
volunteer	Because the function, uh, sorry, go ahead, ask your question.	21,191	570	[]
student	is this x root?	21,191	571	[]
volunteer	Well,	21,191	572	[]
volunteer	Let's give an example. Try using X is equal to.	21,191	573	[]
volunteer	Negative	21,191	574	[]
volunteer	Um, 0.25.	21,191	575	[]
volunteer	Right? And solve that into your	21,191	576	[]
volunteer	Um, G of X.	21,191	577	[]
volunteer	I had to clear the board.	21,191	578	[]
volunteer	All your wonderful work unfortunately, has to.	21,191	579	[]
volunteer	pay the piper.	21,191	580	[]
student	i can solve on my notebook	21,191	581	[]
volunteer	OK. So try solving, um, the 9 X minus 8 square root of x.	21,191	582	[]
volunteer	Um, minus 1 when X is equal to -0.25.	21,191	583	[]
student	when i put x=-0.25 in g(x)	21,191	584	[]
student	it gives -16	21,191	585	[]
volunteer	Did you solve it on your calculator?	21,191	586	[]
volunteer	Or did you solve it by hand?	21,191	587	[]
student	calculator	21,191	588	[]
volunteer	That doesn't seem right.	21,191	589	[]
volunteer	Did, you're not doing square, you're not doing y squad, are you?	21,191	590	[]
student	no	21,191	591	[]
