Question

How do you find the function values f(3a) given F(x) = -4x?

Answer 1

See the entire solution process belowL

Explanation:

To find `f(3a)` we need to 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 xx color(red)(3a)`

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