00:01
All right, here we go.
00:02
So here we are given this function where it says y is the absolute value of x divided by x.
00:14
And so it asks us to use a graphing application.
00:17
I'm a big fan of desmos.
00:19
So i've entered the function here into desmos.
00:22
You can see over here on the side.
00:24
All right.
00:24
And you can see, whoa, you can see that the function is basically two sort of horizontal.
00:32
Of lines.
00:34
It's a little bit tough to see what happens right at zero, though.
00:38
So i'm going to zoom in a little bit.
00:41
Let's see if we can find out a little bit more of what's going on there.
00:45
And i clicked it and it says that, oh, zero is undefined.
00:49
Okay.
00:50
So remember, your domain is the list of possible inputs.
00:54
It's basically what are your x values that you can have? and it looks like here, it's all real numbers except at zero.
01:01
Okay.
01:02
So let's imbiggin this real quick...
