Hello!
On the graph, when the X values are between 4 and 8, they are being constant. The X values between 4 and 8 are constant because the line shown between 4 and 8 on the graph show the line as a straight line. It is not going up nor is it going down, so you can conclude that the X values are not increasing or decreasing.
I hope this helps!
