00:00:00.420 --> 00:00:02.830 A:middle L:90%
in this fellow we're gonna function in west aren't every
2
00:00:02.830 --> 00:00:05.000 A:middle L:90%
divine the domain of dysfunction. Let's start from the
3
00:00:05.019 --> 00:00:09.189 A:middle L:90%
narrative at prom effects were gonna his portion also election
4
00:00:09.580 --> 00:00:15.349 A:middle L:90%
their job function the numerator multiplied by function denominator minus
5
00:00:15.740 --> 00:00:19.149 A:middle L:90%
function in the numerator multiplied by defamatory bunch of India
6
00:00:19.149 --> 00:00:24.350 A:middle L:90%
. No matter which is negative for about it by
7
00:00:24.359 --> 00:00:30.190 A:middle L:90%
function in the denominator squared. All right, let's
8
00:00:30.640 --> 00:00:32.780 A:middle L:90%
, uh, since we have explain this morning and
9
00:00:32.780 --> 00:00:35.539 A:middle L:90%
denominated here, let's divide and multiply in a first
10
00:00:35.539 --> 00:00:38.039 A:middle L:90%
term, uh, under new ranger by X minus
11
00:00:38.039 --> 00:00:45.280 A:middle L:90%
one. So we have exploit us for brightness explained
12
00:00:45.280 --> 00:00:49.829 A:middle L:90%
swarm of connection. Like explain this one. Well
13
00:00:49.829 --> 00:00:55.009 A:middle L:90%
, thanks. Divided by X minus one times one
14
00:00:55.009 --> 00:00:58.250 A:middle L:90%
minus. Next lawyer Explain this one. It's where
15
00:00:58.640 --> 00:01:00.600 A:middle L:90%
All right. We can then right to preserve it
16
00:01:00.600 --> 00:01:04.849 A:middle L:90%
in a family of ice as treks minus one minus
17
00:01:06.239 --> 00:01:07.989 A:middle L:90%
Explain its full in times next year longer explain this
18
00:01:07.989 --> 00:01:11.840 A:middle L:90%
. Would you write it by x minus? Well
19
00:01:11.840 --> 00:01:15.810 A:middle L:90%
, in times, uh, one minus next log
20
00:01:15.849 --> 00:01:19.489 A:middle L:90%
. Excellent. Swollen for all right. Now we're
21
00:01:19.489 --> 00:01:25.420 A:middle L:90%
gonna decide on the domain. We know that first
22
00:01:25.420 --> 00:01:26.560 A:middle L:90%
of all, we have natural light of explain this
23
00:01:26.560 --> 00:01:30.780 A:middle L:90%
one in the dino man right here. you know
24
00:01:30.780 --> 00:01:34.209 A:middle L:90%
that? Explain this. One can not be zero
25
00:01:34.219 --> 00:01:38.049 A:middle L:90%
. It actually should be greater than zero. Right
26
00:01:38.640 --> 00:01:40.849 A:middle L:90%
. So to me, that eggs should be greater
27
00:01:40.849 --> 00:01:44.920 A:middle L:90%
than or broker. This is the first condition.
28
00:01:44.930 --> 00:01:49.150 A:middle L:90%
What else, don't you? We also know that
29
00:01:49.739 --> 00:01:56.930 A:middle L:90%
natural law Oh x minus form should be, uh
30
00:01:56.939 --> 00:02:00.469 A:middle L:90%
, cannot be warm. So this cannot be a
31
00:02:00.480 --> 00:02:02.260 A:middle L:90%
war. Why? Because this is one. We
32
00:02:02.260 --> 00:02:06.129 A:middle L:90%
would get zero in the denominator and that would make
33
00:02:06.129 --> 00:02:09.479 A:middle L:90%
dysfunction of bikes. Undefended says nature. Lagerback's minus
34
00:02:09.479 --> 00:02:14.639 A:middle L:90%
one Cannot people with me that experts warn people he
35
00:02:15.099 --> 00:02:19.210 A:middle L:90%
x cannot be going t plus one. So then
36
00:02:19.219 --> 00:02:23.229 A:middle L:90%
we're gonna write the domain. Yes. First part
37
00:02:23.240 --> 00:02:24.810 A:middle L:90%
is we know that extra be great. Once it
38
00:02:24.810 --> 00:02:30.379 A:middle L:90%
will be between four plus four. Union, get
39
00:02:30.379 --> 00:02:31.710 A:middle L:90%
bus form to father to
