Final answer:
The composition (f o g)(x), where f(x) = x and g(x) = 2, is equal to the constant value 2.
Step-by-step explanation:
If f(x) = x and g(x) = 2, to find (f o g)(x), also read as "f composed with g of x", you would substitute g(x) into f(x).
The function g(x) is a constant function where every value of x gives the output 2.
When we compose f(x) and g(x), it means we plug the output of g(x) into the function f(x).
Thus, (f o g)(x) = f(g(x)) = f(2) = 2. The composition of f(x) with g(x) is simply the constant value 2.
