To find the average rate of change of the function \( g \) from \( x = -9 \) to \( x = -5 \), we need to use the formula:

\[
\text{Average Rate of Change} = \frac{\Delta y}{\Delta x} = \frac{g(x_2) - g(x_1)}{x_2 - x_1}
\]

Here, \( x_1 = -9 \) and \( x_2 = -5 \).

From the graph:
- At \( x = -9 \), the \( y \)-value appears to be \( g(-9) = -6 \).
- At \( x = -5 \), the \( y \)-value appears to be \( g(-5) = 8 \).

Plugging these values into the formula, we get:

\[
\text{Average Rate of Change} = \frac{8 - (-6)}{-5 - (-9)} = \frac{8 + 6}{-5 + 9} = \frac{14}{4} = 3.5
\]

Therefore, the average rate of change of the function from \( x = -9 \) to \( x = -5 \) is \( 3.5 \).
