00:01
So we have a function that is continuous on 0, 1.
00:06
This is 0, 1, except at x equals 0 .25.
00:10
So let's mark that here, 2, 5, with f of 0 equals 1, 1 here, and f of 1 equals 3.
00:21
So let's put a 3 up here.
00:23
We want it to be like this.
00:25
Here's x, here's y.
00:28
And we have n equals 2.
00:31
So i'm going to draw a dashed line here.
00:35
We want to show that f may or may not satisfy the inclusion of the intermediate value theorem, which is to say there exists some c in the interval 0, 1, such that f of c is equal to 2.
00:55
Now let's see.
00:56
First, we want to show that it might not satisfy the inclusion of the intermediate value theorem.
01:00
So i'll mark that in red.
01:02
Let's say we have a function that's like this.
01:06
It's discontinuous at x equals 0 .25.
01:12
And we see that, in general, we only have f of x equal to 1 here and f of x equal to 3 up here...
