Take each g(x) function and put the f function in where you see an x in the g function and see if the final result is 12x. Like this for the first choice from your answers:

It's the last one and I will show you why/how.

Your g(x) function is 3x. Where you see the x in that...replace it with the whole f function. So 3x changes to 3(4x). 4x is your f(x). We subbed that in for the x in the g function. What is 3 times 4x?

TY for the medal!
