00:00:01.090 --> 00:00:04.139 A:middle L:90%
Okay, so this is a two part question here
2
00:00:04.150 --> 00:00:07.049 A:middle L:90%
. Were given a graph off at prime and where
3
00:00:07.049 --> 00:00:10.789 A:middle L:90%
has to approximate a slope of at and actually negative
4
00:00:10.800 --> 00:00:13.810 A:middle L:90%
one now, because the slope is the driven,
5
00:00:13.820 --> 00:00:17.010 A:middle L:90%
the function f every different point. We have to
6
00:00:17.010 --> 00:00:24.100 A:middle L:90%
find ash prime of negative. Born using the graph
7
00:00:24.100 --> 00:00:26.039 A:middle L:90%
of a crime. So we have to do is
8
00:00:26.039 --> 00:00:28.449 A:middle L:90%
look up negative one. And it gets to you
9
00:00:28.449 --> 00:00:33.630 A:middle L:90%
that this is approximately negative. One over two Part
10
00:00:33.630 --> 00:00:37.909 A:middle L:90%
B asks us approximate any open intervals on which the
11
00:00:37.909 --> 00:00:41.280 A:middle L:90%
graph of F is increasing and any organ it trickles
12
00:00:41.280 --> 00:00:44.950 A:middle L:90%
and wished a graph of is decreasing. So we
13
00:00:44.950 --> 00:00:50.719 A:middle L:90%
know that is F Crime of X is greater than
14
00:00:50.719 --> 00:00:54.070 A:middle L:90%
zero for all acts. Then app is increasing so
15
00:00:54.070 --> 00:00:59.619 A:middle L:90%
this implies that is increasing and similar. The crime
16
00:00:59.619 --> 00:01:03.259 A:middle L:90%
of axe is less than zero. It implies that
17
00:01:03.270 --> 00:01:07.409 A:middle L:90%
ass is decreasing on those intervals. So, as
18
00:01:07.409 --> 00:01:10.500 A:middle L:90%
you can see on the graph after X is greater
19
00:01:10.500 --> 00:01:12.290 A:middle L:90%
than zero for all acts in the range of negative
20
00:01:12.290 --> 00:01:17.280 A:middle L:90%
too to infinity. And it is less than zero
21
00:01:17.290 --> 00:01:19.409 A:middle L:90%
for all access in the range of native infinity,
22
00:01:19.739 --> 00:01:23.849 A:middle L:90%
two native to all right. That's all
