Answer:
The left side and down direction are negitive, if you add pictures or multiple choice I could help more!
A decreasing function will always have a negative average rate of change.
For a function f(x), we define the average rate of change on an interval (a, b) as:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
Note that b > a, then it is only negative when:
f(b) < f(a).
This is a characteristic of a decreasing function, this means that when we read the graph from left to right, the function goes downwards.
That is the type of graph that always shows a negative average rate of change.
