Hint:
The composition of functions f(x) and g(x) where g(x) is acting first is represented by f(g(x)) or (f ∘ g)(x). It combines two or more functions to result in another function. In the composition of functions, the output of one function that is inside the parenthesis becomes the input of the outside function. i.e.,
- In f(g(x)), g(x) is the input of f(x).
- In g(f(x)), f(x) is the input of g(x).
The correct answer is:
Given :
To find : 
Thus, x
