Consider the function and its inverse. f(x) = x2 + 4 and f-1(x) = - - 4 When comparing the functions using the equations, which conclusion can be made? The domain of f(x) is restricted to x 20, and the domain off'(x) is restricted to x20. The domain of f(x) is restricted to x 0, and the domain off'(x) is restricted to xs 0. The domain of f(x) is restricted to x < 0, and the domain off'(x) is restricted to x2 4. The domain of f(x) is restricted to xs o, and the domain of f'(x) is restricted to xs 4.
