Question

If F(x) = 2x and G(x) = log x, find F [G(x)].
2logx
log2x
2xlogx

Answer 1

the answer is 2 log x

Answer 2

Answer: The correct option is

(A) 2log x.

Step-by-step explanation: We are given the following two functions :

`F(x)=2x,~~~G(x)=\log x.`

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

`F[G(x)]\\\\=F(\log x)\\\\=2\log x.`

Thus, the required expression for F[G(x)] is 2log x.

Option (A) is CORRECT.
