Answer: The correct option is
(A) 2log x.
Step-by-step explanation: We are given the following two functions :
[tex]F(x)=2x,~~~G(x)=\log x.[/tex]
We are to find the expression for F[G(x)].
To find F[G(x)], we have to find F of G(x).
We have
[tex]F[G(x)]\\\\=F(\log x)\\\\=2\log x.[/tex]
Thus, the required expression for F[G(x)] is 2log x.
Option (A) is CORRECT.
