00:00:02.439 --> 00:00:06.089 A:middle L:90%
Okay, so we're given sl black and we need
2
00:00:06.099 --> 00:00:10.300 A:middle L:90%
to find felt such that Jos, listen, actually
3
00:00:10.300 --> 00:00:12.589 A:middle L:90%
, value backs money to is us on Delta.
4
00:00:13.140 --> 00:00:15.769 A:middle L:90%
Then the function that's about all you have are function
5
00:00:15.769 --> 00:00:19.730 A:middle L:90%
. My city is Listen, there is that our
6
00:00:19.739 --> 00:00:24.550 A:middle L:90%
figure that's evaluated at two is equal to three.
7
00:00:26.239 --> 00:00:29.070 A:middle L:90%
And we know that after all of effort, back
8
00:00:29.109 --> 00:00:33.509 A:middle L:90%
when it's free lesson do important for oh, we
9
00:00:33.509 --> 00:00:43.060 A:middle L:90%
have that 1.6 is in effect. Lesson 2.4 if
10
00:00:43.060 --> 00:00:46.310 A:middle L:90%
we, um remover actually valid in and add three
11
00:00:46.310 --> 00:00:55.310 A:middle L:90%
to both sides. Okay, uh, from the
12
00:00:55.320 --> 00:01:00.890 A:middle L:90%
figure we feed at 1.6 is approximately 2.6 and evaluated
13
00:01:00.890 --> 00:01:04.420 A:middle L:90%
at 2.43 point four. So we have that x
14
00:01:04.430 --> 00:01:11.109 A:middle L:90%
minus to invest in Delta such that our function minus
15
00:01:11.120 --> 00:01:14.250 A:middle L:90%
three doctor values of that is us and Joe 30.4
16
00:01:15.140 --> 00:01:19.510 A:middle L:90%
. So this gives that 1.6 is less than X
17
00:01:19.530 --> 00:01:23.379 A:middle L:90%
is less than 2.4. Therefore, delta is our
18
00:01:23.379 --> 00:01:30.890 A:middle L:90%
minimum between two wonderful boys six and two point form
19
00:01:30.890 --> 00:01:34.140 A:middle L:90%
. When it you, which is equal to point
20
00:01:34.150 --> 00:01:38.049 A:middle L:90%
for. That means Delta is equal to 0.4
