Option C is correct. the functions that would not be a possible function for f (x) and g(x) are f(x) = and g(x) = x
Given the composite function
We are to look for two functions f(x) and g(x) that will not give the same function
Using trial and error,
If f(x) = and g(x) = x
Determine the f(g(x)) for this function
f(g(x)) = f(x)
This is gotten by simply replacing x with x in f(x). This will return back the function f(x) making this the right choice.
f(g(x)) =
Since,
, hence the functions that would not be a possible function for f (x) and g(x) are f(x) =
and g(x) = x
