The average rate of change on the interval [-5, -3] is R = 8.
How to get the average rate of change?
For a function f(x), the average rate of change on the interval [x₁, x₂] is given by:
[tex]R = \frac{f(x_2) - f(x_1)}{x_2 - x_1}[/tex]
In this case, we have the interval [-5, -3], by looking at the graph, we can see that:
f(-3) = 1
f(-5) = -15
Then the average rate of change is:
[tex]R = \frac{1 - (-15)}{-3 - (-5)} = 8[/tex]
So the correct option is A.
