1. The answer is 0. The graph of y equals x squared plus one doesn't touch the x
2. axis at all. Let's take a peek at the graph. So here is a beautiful graph of y
3. equals x squared plus one, you can see that the lowest point on the parabola is
4. above the x axis. So, the fact that X squared plus 1 doesn't have any real
5. linear factors means that its graph doesn't intersect the X axis. This is a
6. great example of a lot of the things we've been talking about in this lesson.
