Let's create a graph of our function f of x equals 3 over x.
00:03
To make this graph, we're going to have to plug in some points and see what we get.
00:08
So we can start with f of 1.
00:11
That's just going to give us 3 over 1, which is 3.
00:15
So we can put a point at 1 3.
00:18
Then we could do f of 3, which gives us 3 over 3, which is 1.
00:24
So we can put a point at 3 1.
00:27
If you haven't caught onto the pattern yet, things are going to be sort of mirrored, like this.
00:31
Then if we put f of six, that will give us three over six, which is one half.
00:37
So six, one half.
00:40
And f of one half is going to be three over one half, which is six.
00:46
So once again, mirrored to put it up here.
00:49
And then what about the negatives? well, for these, you can see that putting in a negative would actually just make this entire thing negative.
00:56
So f of negative one is negative 3.
00:59
F of negative 3 is negative 1, and so on...
