Now you did up here.
21,191
692
[]
volunteer
You had 81 x minus 1 times X minus 1. Let's try that.
21,191
693
[]
student
no, it's correct
21,191
694
[]
volunteer
81 X minus 1 times X minus 1.
21,191
695
[]
volunteer
Yeah.
21,191
696
[]
volunteer
Those aren't the same.
21,191
697
[]
volunteer
Oh, I'm sorry, I didn't show you the graph.
21,191
698
[]
volunteer
But we see we get um you can't tell, but they're the red graph, the original 81 a minus 82 + 1.
21,191
699
[]
volunteer
They're, they're both the same, these two expressions when it's factored. But you see, you still don't get the same behavior that you do with our G of X.
21,191
700
[]
student
yeah
21,191
701
[]
volunteer
This is like this black or the equation you're finding is G of X^2.
21,191
702
[]
volunteer
So what if we took
21,191
703
[]
volunteer
The
21,191
704
[]
volunteer
Square root of this whole thing.
21,191
705
[]
volunteer
Uh.
21,191
706
[]
volunteer
Would you look at that.
21,191
707
[]
student
it's different from g(x)\
21,191
708
[]
volunteer
Let me try.
21,191
709
[]
volunteer
It's diff you're saying it's different, so let's try the negative. If I have to include.
21,191
710
[]
volunteer
A go though, huh, there it is.
21,191
711
[]
volunteer
Just as drastic squares it.
21,191
712
[]
volunteer
It's different from GOX.
21,191
713
[]
volunteer
But you're taking your GFX.
21,191
714
[]
volunteer
Um
21,191
715
[]
volunteer
And at some point you're squaring the whole equation.
21,191
716
[]
volunteer
Oh, you're saying you specifically define G of X is equal to 0.
21,191
717
[]
volunteer
And then squared it. So only at x equals 0 with this.
21,191
718
[]
volunteer
Expression hold.
21,191
719
[]
volunteer
81 X minus 1 times X minus 1.
21,191
720
[]
student
yeah
21,191
721
[]
volunteer
in the function, when the function is equal to 0.
21,191
722
[]
volunteer
Oh, basically the X intercepts.
21,191
723
[]
volunteer
Yeah
21,191
724
[]
student
yes
21,191
725
[]
volunteer
Damn, you're outsmarting me.
21,191
726
[]
volunteer
Hm
21,191
727
[]
volunteer
Oops did not curse. I said dang.
21,191
728
[]
volunteer
I apologize.
21,191
729
[]
volunteer
I can use.
21,191
730
[]
student
I thought you knew it.
21,191
731
[]
student
therfore i didn't mention it
21,191
732
[]
volunteer
I think I got confused because I was graphing um
21,191
733
[]
volunteer
G of Y, which was
21,191
734
[]
volunteer
Basically where Y is equal, where X is equal to k.
21,191
735
[]
volunteer
So my coefficients were the exact same as G of X.
21,191
736
[]
student
yeah
21,191
737
[]
volunteer
Hm
21,191
738
[]
volunteer
Yeah, still.
21,191
739
[]
volunteer
But I still believe
21,191
740
[]
volunteer
That
21,191
741
[]
volunteer
The function G oh, what just happened?
21,191
742
[]
volunteer
Sorry, Sam.
21,191
743
[ { "pii_type": "PERSON", "surrogate": "Sam", "start": 7, "end": 10 } ]
volunteer
To be relaxed for a second.
21,191
744
[]
volunteer
Um,
21,191
745
[]
volunteer
I still think
21,191
746
[]
volunteer
I still think because of this square root of X.
21,191
747
[]
volunteer
That
21,191
748
[]
volunteer
X has to be positive. It can't be negative.
21,191
749
[]
volunteer
Even if, cause if you have to, if you have to manipulate it.
21,191
750
[]
volunteer
Well
21,191
751
[]
volunteer
Uh, I guess even if you manipulate it because the parabola is still a parabola, right? A function is still a function even if it's just a different form or you.
21,191
752
[]
student
yeah
21,191
753
[]
student
it won't change
21,191
754
[]
volunteer
Still, though,
21,191
755
[]
volunteer
Um, if we look at the answers,
21,191
756
[]
volunteer
They're specifying integers.
21,191
757
[]
volunteer
So we focus on that. How does that change?
21,191
758
[]
volunteer
What we've been doing.
21,191
759
[]
volunteer
looking for.
21,191
760
[]
student
ohh, I didn't focus on that
21,191
761
[]
student
I think 1/81 got dismissed becuz it isn't an integer
21,191
762
[]
student
it is real but not integer
21,191
763
[]
volunteer
Yeah.
21,191
764
[]
volunteer
I think, I think because just like we're having this big debate.
21,191
765
[]
volunteer
On whether there's two real roots or not, or if there's just one in one complex. I think they wanted to mitigate that and just.
21,191
766
[]
volunteer
Just so there's no ambiguity.
21,191
767
[]
volunteer
In the test.
21,191
768
[]
student
yeah, both are real roots but only of em is integer
21,191
769
[]
volunteer
OK. Well, that's that problem.
21,191
770
[]
volunteer
Do you have any more? I gotta, I gotta get going.
21,191
771
[]
volunteer
You wake up early.
21,191
772
[]
student
I don't have any more problem
21,191
773
[]
student
if you want, we can take tomorrow off
21,191
774
[]
volunteer
Yeah, so if you want to do that, we can wait till Monday evening.
21,191
775
[]
student
I mean monday off, then start from tuesday.
21,191
776
[]
volunteer
Oh, OK.
21,191
777
[]
volunteer
is to tomorrow night.
21,191
778
[]
volunteer
OK, that's fine. We want to start again on Tuesday.
21,191
779
[]
volunteer
Take 2 days off.
21,191
780
[]
student
it;s just one day off --> monday
21,191
781
[]
student
we did class today
21,191
782
[]
volunteer
Right, and today is, oh, it's Sunday right now.
21,191
783
[]
volunteer
Right
21,191
784
[]
volunteer
So we can
21,191
785
[]
volunteer
Meat
21,191
786
[]
volunteer
2 Tuesday night, Tuesday evening.
21,191
787
[]
student
yes
21,191
788
[]
student
8pm
21,191
789
[]
volunteer
All right. Well then, have a good couple of days, and I'll see you.
21,191
790
[]
volunteer
Tuesday.
