We have to check which of PEMDAS rules can be applied in this case. We have only ADDITION. In this case we can observe that addition is:
1. Associative
2. Commutative
3. has Additive property

The average rate of change over the interval (-3, 2) is 1
<h3>Average rate of change</h3>The average rate of change of a function, graph, table or ordered pair is simply the slope of the relation
<h3>Interval</h3>The interval is given as: (-3,2)
From the graph, we have:
- f(-3) = -5
- f(2) = 0
So, the average rate over these intervals is calculated as:
This gives
Substitute known values
Simplify
Hence, the average rate of change is 1
