1. **State the problem:** Evaluate the function $f(x) = x^3 - 4x^2 - 11x + 30$ at $x = -3$.
2. **Recall the formula:** To find $f(-3)$, substitute $x$ with $-3$ in the function.
3. **Substitute and calculate:**
$$f(-3) = (-3)^3 - 4(-3)^2 - 11(-3) + 30$$
4. **Simplify powers:**
$$= -27 - 4(9) + 33 + 30$$
5. **Multiply:**
$$= -27 - 36 + 33 + 30$$
6. **Add and subtract step-by-step:**
$$-27 - 36 = -63$$
$$-63 + 33 = -30$$
$$-30 + 30 = 0$$
7. **Final answer:**
$$f(-3) = 0$$
So, when $x = -3$, $f(x) = 0$.
This means the function value at $x = -3$ is 0.
