The image you uploaded asks to find the average rate of change of the function $f(x)$ over the interval $-6 \leq x \leq -2$. To proceed, I need the graph of $f(x)$ that the question references, but it is not visible in the current upload.

To find the average rate of change of $f(x)$ over the given interval, we would typically use the formula:

$\text{Average Rate of Change} = \frac{f(b) - f(a)}{b - a}$

where $a = -6$ and $b = -2$.

Please ensure that the graph of $f(x)$ is included, or provide the values of $f(-6)$ and $f(-2)$, and I'll help you calculate the average rate of change.

Would you like to upload the graph or share the needed values?
