The average rate of change from x=1 to x=3 is -1
On the given graph, we have the following function values
f(1) = 6
f(3) = 4
The average rate of change from x=1 to x=3 is then calculated as
Rate = [f(3) - f(1)]/[3 - 1]
This gives
Rate = [4 - 6]/[3 - 1]
Evaluate
Rate = -1
Hence, the average rate of change from x=1 to x=3 is -1
