The given problem asks to evaluate $(f \circ g)(-1)$, which represents the composition of the functions $f$ and $g$, evaluated at $-1$.

Steps to solve:

1. Find $g(-1)$:
   From the table, look at the value of $g(x)$ when $x = -1$.
   $g(-1) = -2$

2. Find $f(g(-1))$:
   Now that we know $g(-1) = -2$, we need to find $f(-2)$. Look at the value of $f(x)$ when $x = -2$.
   $f(-2) = 9$

Thus, $(f \circ g)(-1) = f(g(-1)) = f(-2) = 9$.

The final answer is 9.
