Find (f/g)(x) and (8/f)(x) for the functions given by f(r) = r and
g(x) = /4-. Then find the domains of f/lg and g/f.

Composition of Functions
Definition of Composition of Two Functions- The composition of the function of f with the
function g is: (fo g) (x) =f(g (x)).
The domain of (fo g) is the set of all x in the domain of g such that g (x) is in the domain of f.
For instance, iff (x)= x² and g (x) = x+1, the composition of f with g is: f(g (x)) = (x+1)
