See below.

#### Explanation:

All you have to do is substitute $- 4$ for $x$ in the given function $f \left(x\right) = 3 - 6 x$:

$f \left(x\right) = 3 - 6 x$
$f \left(- 4\right) = 3 - 6 \left(- 4\right)$
$f \left(- 4\right) = 3 + 24$
$f \left(- 4\right) = 27$

Therefore, your final answer would be $f \left(- 4\right) = 27$.

I hope that helps!
