Hello!
The answer is: The correct option is the second option, 2.
Why?
We are working with composite functions. Composite functions mean to evaluate a function in another function.
Composite function:
[tex](f\circ g)(x)=f(g(x))[/tex]
So, for this case, where there is a variable "x" we need to rewrite it with the function g(x)
Then,
[tex](f\circ g)(x)=(g(x))=(2)\\(f\circ g)(x)=2[/tex]
Hence, the correct option is the second option, 2.
Have a nice day!
