student
So I'veMX.
16,143
628
[]
student
is
16,143
629
[]
student
uh
16,143
630
[]
student
honestly
16,143
631
[]
student
Um, how do I do it
16,143
632
[]
volunteer
Mhm
16,143
633
[]
volunteer
So, is that the same problem
16,143
634
[]
student
Oh yeah
16,143
635
[]
volunteer
That one?
16,143
636
[]
student
Mhm
16,143
637
[]
volunteer
How would you, what would this equal to?
16,143
638
[]
student
The X, so it's uh, uh, I square minus 3 X.
16,143
639
[]
student
right?
16,143
640
[]
volunteer
Yeah?
16,143
641
[]
student
OK.
16,143
642
[]
volunteer
But this is F, so that would be F of X. But so what would F G X be?
16,143
643
[]
student
Fenyx. You mean GF GF would be 33 X 1 is 2.
16,143
644
[]
volunteer
Mhm
16,143
645
[]
student
Mm
16,143
646
[]
student
So
16,143
647
[]
student
Uh, so, wait, I don't get it. I'm sorry.
16,143
648
[]
volunteer
That's OK. So
16,143
649
[]
student
No, I
16,143
650
[]
volunteer
you
16,143
651
[]
student
no, I would be uh X squared minus 3X. How come it's 3 X? That's why I'm not trying to understand.
16,143
652
[]
volunteer
OK
16,143
653
[]
volunteer
So
16,143
654
[]
volunteer
that would be
16,143
655
[]
volunteer
let's see if I can
16,143
656
[]
volunteer
make up more sense
16,143
657
[]
volunteer
Now, let me, let me try to ride it out. So F of
16,143
658
[]
volunteer
G of X
16,143
659
[]
volunteer
would be F of 3 x minus 2.
16,143
660
[]
volunteer
right? Cause that's what GFX equals to.
16,143
661
[]
volunteer
So now, instead of just, so this is what F of X would be.
16,143
662
[]
volunteer
X squared minus 3 X.
16,143
663
[]
volunteer
wherever you see the X.
16,143
664
[]
volunteer
you plug in X or whatever number.
16,143
665
[]
volunteer
So when
16,143
666
[]
volunteer
we have 3 x minus 2.
16,143
667
[]
volunteer
or let's say X + 1.
16,143
668
[]
volunteer
Wherever you have the X, that's the input.
16,143
669
[]
volunteer
you would add one to it.
16,143
670
[]
volunteer
though X + 1
16,143
671
[]
volunteer
squad
16,143
672
[]
volunteer
minus 3.
16,143
673
[]
volunteer
and then that would have to add one too.
16,143
674
[]
volunteer
So when the input is changed, right, this is the transformation
16,143
675
[]
volunteer
instead of just X
16,143
676
[]
volunteer
Now we have 3 x minus 2.
16,143
677
[]
volunteer
though.
16,143
678
[]
volunteer
if it makes sense
16,143
679
[]
volunteer
this is a 3
16,143
680
[]
volunteer
Wherever we see the X, we have to transform it, so.
16,143
681
[]
volunteer
if it's
16,143
682
[]
volunteer
X squared, then it becomes
16,143
683
[]
volunteer
3 X minus 2
16,143
684
[]
volunteer
2
16,143
685
[]
volunteer
So
16,143
686
[]
volunteer
if we say X is 1.
16,143
687
[]
volunteer
then we would transform it to be 3 times 1.
16,143
688
[]
volunteer
minus 2
16,143
689
[]
volunteer
but
16,143
690
[]
volunteer
the way we're doing it, we're using more symbols.
16,143
691
[]
volunteer
instead of the numbers, but they're the same thing. We put the symbol in place of the number.
16,143
692
[]
volunteer
So Xs are variable, they call it.
16,143
693
[]
student
Mm
16,143
694
[]
volunteer
So how would you do
16,143
695
[]
volunteer
the next part, minus 3 X. What would that look like?
16,143
696
[]
student
So you got one.
16,143
697
[]
volunteer
Mhm.
16,143
698
[]
student
you plug it out, so there'll be this one, OK.
16,143
699
[]
student
So
16,143
700
[]
student
X
16,143
701
[]
student
+ 1
16,143
702
[]
student
Then again, X + 1.
16,143
703
[]
student
plus
16,143
704
[]
student
1 in 3 x
16,143
705
[]
volunteer
Mhm.
16,143
706
[]
student
plus.
16,143
707
[]
student
1, and then
16,143
708
[]
student
based on that, we just solve it.
16,143
709
[]
volunteer
Yup
16,143
710
[]
student
So that'll be
16,143
711
[]
student
so
16,143
712
[]
student
SS squad
16,143
713
[]
student
and then one plus.
16,143
714
[]
student
1 X
16,143
715
[]
student
+
16,143
716
[]
volunteer
Mhm.
16,143
717
[]
student
1 X again
16,143
718
[]
student
um plus 2
16,143
719
[]
student
and then minus
16,143
720
[]
student
3 X
16,143
721
[]
student
uh, and then minus.
16,143
722
[]
student
3
16,143
723
[]
student
and then we combine like terms, so.
16,143
724
[]
volunteer
Uh, I would look at this one again. The last one plus
16,143
725
[]
volunteer
the last term
16,143
726
[]
volunteer
it should just
16,143
727
