The average rate of change on that interval is r = 7/3.
<h3>How to find the average rate of change on the interval?</h3>
For any function f(x), we define the average rate of change on an interval [a, b] as:
r = ( f(b) - f(a))/(b - a)
In this case, the interval is [0, 6], using the graph we can find the values of the function for these inputs:
f(0) = -8
f(6) =6
Replacing that we get:
r = (6 - (-8))/(6 - 0)
r = (6 + 8)/6
r = 14/6
r = 7/3
The average rate is 7/3.
