Question

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

Answer 1

See the entire solution process below:

Explanation:

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`
