00:00:02.839 --> 00:00:04.650 A:middle L:90%
we're going to find the domain of this function.
2
00:00:05.240 --> 00:00:08.570 A:middle L:90%
And so a lot of times it works really well
3
00:00:08.580 --> 00:00:10.650 A:middle L:90%
. If you think about the parent function, that
4
00:00:10.650 --> 00:00:13.500 A:middle L:90%
is the simplified version of your function. So here
5
00:00:13.500 --> 00:00:15.900 A:middle L:90%
we see a cube root function, I would call
6
00:00:15.900 --> 00:00:18.480 A:middle L:90%
its parent function F of T equals a Q Bert
7
00:00:18.480 --> 00:00:21.629 A:middle L:90%
of teeth. That's the most basic you brew function
8
00:00:21.960 --> 00:00:24.260 A:middle L:90%
on picture what that looks like. Hopefully you have
9
00:00:24.260 --> 00:00:25.890 A:middle L:90%
a picture of that in your mind. If not
10
00:00:25.890 --> 00:00:28.399 A:middle L:90%
, you could use a calculator or something that would
11
00:00:28.399 --> 00:00:31.019 A:middle L:90%
give you a graph. Something like that, and
12
00:00:31.019 --> 00:00:34.200 A:middle L:90%
its domain would be all real numbers. Well,
13
00:00:34.380 --> 00:00:37.009 A:middle L:90%
how do we get from that to the function were
14
00:00:37.009 --> 00:00:40.380 A:middle L:90%
interested in because of the to hear there's some sort
15
00:00:40.380 --> 00:00:43.359 A:middle L:90%
of horizontal stretch or shrink that would not change the
16
00:00:43.359 --> 00:00:46.049 A:middle L:90%
domain. And because of the minus one here,
17
00:00:46.049 --> 00:00:49.380 A:middle L:90%
there's some kind of horizontal shift that would not change
18
00:00:49.380 --> 00:00:51.899 A:middle L:90%
the domain either. So the domain of our function
19
00:00:51.899 --> 00:00:54.090 A:middle L:90%
is all real numbers, and if you prefer to
20
00:00:54.090 --> 00:00:56.820 A:middle L:90%
write that using interval notation, you can use the
21
00:00:56.829 --> 00:00:59.270 A:middle L:90%
notation negative infinity to infinity
