To find the average rate of change of a function on an interval, we use the formula:
(Average Rate of Change) = [f(b) - f(a)] / (b - a)
In this case, our interval is from -8 to -6. So a = -8, b = -6.
Therefore, the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -6 is:
[f(-6) - f(-8)] / (-6 - (-8)) = [f(-6) - f(-8)] / 2
From the graph provided, we can see that f(-8) = 4 and f(-6) = 2.
So, the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -6 is:
[2 - 4] / 2 = -2 / 2 = -1
(Average Rate of Change) = [f(b) - f(a)] / (b - a)
In this case, our interval is from -8 to -6. So a = -8, b = -6.
Therefore, the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -6 is:
[f(-6) - f(-8)] / (-6 - (-8)) = [f(-6) - f(-8)] / 2
From the graph provided, we can see that f(-8) = 4 and f(-6) = 2.
So, the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -6 is:
[2 - 4] / 2 = -2 / 2 = -1
