Chain Rule
1. We are given the function composition $F(x) = f(g(x))$. The problem asks for the derivative $F'(-3)$.
2. By the chain rule, the derivative of $F$ at $x$ is
$$F'(x) = f'(g(x)) \cdot g'(x).$$
3. To find $F'(-3)$, substitute $x = -3$:
$$F'(-3) = f'(g(-3)) \cdot g'(-3).$$
4. From the problem, we know:
- $g(-3) = -2$
- $g'(-3) = 5$
- $f'(-2) = 6$
5. Substitute these values:
$$F'(-3) = f'(-2) \cdot 5 = 6 \cdot 5 = 30.$$
