00:00:00.800 --> 00:00:03.169 A:middle L:90%
okay for this question Over here, we know we're
2
00:00:03.169 --> 00:00:06.240 A:middle L:90%
trying to figure out where is F Conkey downward?
3
00:00:06.559 --> 00:00:07.940 A:middle L:90%
In order to do that, we know we're gonna
4
00:00:07.940 --> 00:00:10.640 A:middle L:90%
have to calculate the first and the second derivative.
5
00:00:11.439 --> 00:00:17.780 A:middle L:90%
Okay, so given this we know after box is
6
00:00:18.239 --> 00:00:22.289 A:middle L:90%
intro from wonder Acts of off of T Do you
7
00:00:22.289 --> 00:00:25.730 A:middle L:90%
achieve? Remember, we have the fear of the
8
00:00:25.730 --> 00:00:28.750 A:middle L:90%
f Prime of axe is lower case of the vax
9
00:00:29.239 --> 00:00:35.039 A:middle L:90%
therefore off Double problem Max is lower case off Problem
10
00:00:35.640 --> 00:00:38.619 A:middle L:90%
X Therefore, we know the given graph is decreasing
11
00:00:38.619 --> 00:00:40.929 A:middle L:90%
on the interval. Negative 1 to 1. Therefore
12
00:00:40.929 --> 00:00:43.320 A:middle L:90%
we know it is Kong Cave down on the interval
13
00:00:43.329 --> 00:00:44.450 A:middle L:90%
. Negative 1 to 1.
