Answer: The correct option is
(C)
Step-by-step explanation: We are given the following two functions :

We are to find the value of h(x) if h(x) = f(x) - g(x).
To find the value of h(x), we must subtract the expression of g(x) from the expression of f(x).
The value of h(x) can be calculated as follows :

Thus, the required value of h(x) is

Option (C) is CORRECT.
