f(x) = x^2 g(x) = √(1-x)
The Domain of (f∘g)(x) is :
(f∘g)(x) =
The Domain of (g∘f)(x) is :
(g∘f)(x) =

  1. (f∘g)(x) = [ √(1-x) ]^2 = 1-x all real x

    (g∘f)(x) = √(1-x^2) which is imaginary for |x| >1 so only from x = -1 to x =+1

    Remember that f(x) must be one-to-one (only one y-value for each x-value) over the domain where f –1(x)is defined as a function. So, in some cases you must restrict the domain of f(x) so that it's one-to-one. There might be more
