Answer 1

Answer: Second option.

Step-by-step explanation:

Given the function f(x), which is:

$f(x)=x$

And given the function g(x), which is:

$g(x)=2$

You need to substiute the function $g(x)=2$  into the function  $f(x)=x$ in order to find $(fog)(x)$.

Therefore, through this procedure, you get this answer:

$(fog)(x)=(2)$

$(fog)(x)=2$

You can observe that this matches with the second option.

Answer 2

For this case we have the following functions:

$f (x) = x\\g (x) = 2$

We must find $(f_ {0} g) (x).$

By definition of composite functions we have to:

$(f_ {0} g) (x) = f (g (x))$

We substitute g (x) into f (x), then we have:

$f (g (x)) = 2$

Answer:

$f (g (x)) = 2$
