What are the domain and range of the function below?

Apossible answer: f(x) = 2*sqrt(x)g(x) = x + 8we want to make h(x) a composite function.g(x) is the inside function. f(x) is the outside.at a glance, it looks like h(x) = 2√(x+8) has an "inside" expression of x+8 and an outside shell of 2√(stuff).so if we choose f(x) = 2√(x) and g(x) = x + 8, this will compose ash(x) = f( g(x) )        = 2√(x+8)
