Find the domain of f composition g x for the function fx an

Find the domain of (f composition g) (x) for the function f(x) = and g(x) = x^2 + 4

Solution

since function f(x) is not provided in the question, generally to find the domain of the composite function put g(x) at the place of every x in f(x) and simplify. and then for this new function find all values of x for which the function is defined.
