Yes. Close. So when you married here,
2
00:00:03.240 --> 00:00:07.230 A:middle L:90%
so we have ever backs is equal to x square
3
00:00:07.230 --> 00:00:13.859 A:middle L:90%
minus one times e to the X. We're gonna
4
00:00:13.869 --> 00:00:24.420 A:middle L:90%
find our derivative by using the product rule yet to
5
00:00:24.429 --> 00:00:30.250 A:middle L:90%
ex homes, Eat the X goes eat two x
6
00:00:32.039 --> 00:00:36.630 A:middle L:90%
times X square minus one. This is equal to
7
00:00:36.640 --> 00:00:42.649 A:middle L:90%
eat the X x square plus to minus one.
8
00:00:45.679 --> 00:00:50.899 A:middle L:90%
To get our second derivative, we're gonna use the
9
00:00:50.899 --> 00:00:55.509 A:middle L:90%
product rule again. Get E to the X from
10
00:00:55.509 --> 00:01:03.210 A:middle L:90%
specs square Those two X minus one must two X
11
00:01:03.210 --> 00:01:10.489 A:middle L:90%
plus two e to the X, which is equal
12
00:01:10.489 --> 00:01:15.560 A:middle L:90%
to eat The axe. Times Square was for X
13
00:01:15.560 --> 00:01:25.510 A:middle L:90%
plus one. Next, we're going to draw our
14
00:01:25.519 --> 00:01:38.450 A:middle L:90%
graphs wound. Don't look like this.
