00:00:00.440 --> 00:00:06.150 A:middle L:90%
wow in this problem, we want to identify how
2
00:00:06.160 --> 00:00:08.839 A:middle L:90%
each graph is obtained from the graph of fx for
3
00:00:08.849 --> 00:00:13.560 A:middle L:90%
a through F. As the note at the top
4
00:00:13.560 --> 00:00:16.170 A:middle L:90%
of this page indicate we're gonna rely on knowledge of
5
00:00:16.170 --> 00:00:18.579 A:middle L:90%
transformation for the graphs. We wanted to be answer
6
00:00:18.589 --> 00:00:22.870 A:middle L:90%
how these graphs are being the affects that relates to
7
00:00:22.870 --> 00:00:27.969 A:middle L:90%
translations, reflections, enlargement and other transformations. So
8
00:00:27.969 --> 00:00:32.420 A:middle L:90%
for instance in a move why people that express eight
9
00:00:32.429 --> 00:00:34.159 A:middle L:90%
we'll be N. Y equals mx plus A.
10
00:00:34.159 --> 00:00:36.070 A:middle L:90%
Which is known as a vertical shift. Thus we
11
00:00:36.070 --> 00:00:39.840 A:middle L:90%
translate the graft upwards eight from fx. For being
12
00:00:39.840 --> 00:00:42.560 A:middle L:90%
we have Y equals X plus eight. This is
13
00:00:42.560 --> 00:00:44.909 A:middle L:90%
known as X minus a horizontal shift. So for
14
00:00:44.909 --> 00:00:47.880 A:middle L:90%
x minus a or a is negative eight. We
15
00:00:47.880 --> 00:00:52.119 A:middle L:90%
have shift left eight proceeding of Y equals the fx
16
00:00:52.130 --> 00:00:55.100 A:middle L:90%
. This is an enlargement, vertical stretch being factor
17
00:00:55.109 --> 00:00:58.960 A:middle L:90%
eight. And do we have Y equals X.
18
00:00:58.969 --> 00:01:02.100 A:middle L:90%
This is an enlargement. So it's when we multiply
19
00:01:02.100 --> 00:01:03.900 A:middle L:90%
the number eight inside the parentheses outside the prime T
20
00:01:03.900 --> 00:01:06.989 A:middle L:90%
. V. As in part C. We're now
21
00:01:06.989 --> 00:01:08.569 A:middle L:90%
doing a horizontal stretch by a factor eight. This
22
00:01:08.569 --> 00:01:11.799 A:middle L:90%
is the different vertical and horizontal stretching and we have
23
00:01:11.799 --> 00:01:15.400 A:middle L:90%
Y equals negative fx minus one. This is two
24
00:01:15.400 --> 00:01:17.439 A:middle L:90%
transformation. So but first we've got to have the
25
00:01:17.439 --> 00:01:21.049 A:middle L:90%
X axis that's for Y equals negative fx. And
26
00:01:21.049 --> 00:01:23.500 A:middle L:90%
then similar to the question A we have a vertical
27
00:01:23.500 --> 00:01:25.560 A:middle L:90%
shift, We're here, we're shipping one year down
28
00:01:25.560 --> 00:01:27.489 A:middle L:90%
minus one. Finally, and F we have Y
29
00:01:27.489 --> 00:01:30.319 A:middle L:90%
equals eight. F. 28 X. This combined
30
00:01:30.319 --> 00:01:34.430 A:middle L:90%
their knowledge from CMD. So we have a vertical
31
00:01:34.430 --> 00:01:37.219 A:middle L:90%
stretch factor eight and a horizontal shrink by a factor
32
00:01:37.230 --> 00:01:41.359 A:middle L:90%
8 to 18 graph of Y equals eight F 20
33
00:01:41.370 --> 00:01:42.370 A:middle L:90%
X from fx.
