Okay.
00:01
So the easiest way to graph this is to start with your x, y chart and just pick some values.
00:06
I'm going to start with negative one, zero, one, two, three.
00:13
Now, i know that some of this is not going to work out, but i just want to show you.
00:17
So in your calculator, negative 2 .5, natural log, negative one.
00:25
That gives me a domain arrow, so that is undefined.
00:29
Now, i'm going to do the same thing again, and i'm just, i know that this graph is not going to cross the x axis.
00:36
I mean the y axis, but if i didn't know that, this is how i would check it.
00:43
This is also undefined.
00:45
So i know that my x values, i have no values that are negative past zero.
00:52
All right.
00:53
So now i'm going to do the same thing with one, plug in one.
00:56
So negative 2 .5, natural log one.
01:01
That gives me zero.
01:06
So one, zero.
01:09
That's my first point.
01:13
Negative 2 .5, natural log two.
01:26
Negative 1 .73.
01:30
And then plug in three.
01:33
So negative 2 .5, natural log three.
01:39
That gives me negative 2 .75.
01:45
So two, one, two...
