To find \( f(-6) \) given the function \( f(x) = -3x^2 - 3x \), we can substitute \(-6\) into the function.

\[
f(-6) = -3(-6)^2 - 3(-6)
\]

Calculating each term:

1. Calculate \((-6)^2\):
\[
(-6)^2 = 36
\]

2. Compute \(-3(-6)^2\):
\[
-3(36) = -108
\]

3. Compute \(-3(-6)\):
\[
-3(-6) = 18
\]

Now combine these results:

\[
f(-6) = -108 + 18 = -90
\]

Thus, \( f(-6) = -90 \).

Therefore, the answer is:

\[
f(-6) = -90
\]
