What is happening to this graph when the x-values are between 4 and 8?
Vilka [71]

Answer:

The correct answer is A. It is constant.

Step-by-step explanation:

When the x-values are between 4 and 8, this graph is constant.  This can be seen because the graph is a horizontal line, meaning it has zero slope.  Since the slope is zero, it is neither increasing nor decreasing, and is known as constant.

Hope this helps!
