See the entire solution process below:

To find $f(3a)$ substitute $color(red)(3a)$ for every occurrence of $color(red)(x)$ in the function:

$f(color(red)(x)) = -4color(red)(x)$ becomes:

$f(color(red)(3a)) = -4(color(red)(3a))$

$f(color(red)(3a)) = -12a$

For F(x) = -4xF(x) = -4x how do you find f(3a)?
