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

 The correct option is

(A) 2log x.

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

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

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

Option (A) is CORRECT.

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.
