Answer:

None of them.

Step-by-step explanation:

you want to find the least value of x for which f(x)>g(x). Then replacing both expressions we have

$4x>5x+2\rightarrow -2>5x-4x=x$ . This means that for f to be greater than g, x should be less than -2. Since we are considering x>0, given that it represents years (which are always positive), the question does not have a correct answer.
