Consider the function and its inverse. f(x) = x ^ 2 + 4 and f ^ - 1 * (x) = - sqrt(x - 4) When comparing the functions using the equations, which conclusion can be made? OThe domain of f(x) is restricted to x >= 0 , and the domain of f ^ - 1 * (x) is restricted to x >= 0 . The domain of f(x) is restricted to x >= 0 , and the domain of f ^ - 1 * (x) is restricted to x <= 0 . The domain of f(x) is restricted to x <= 0 , and the domain of f ^ 1 * (x) is restricted to x >= 4 . The domain of f(x) is restricted to x <= 0 , and the domain off f ^ - 1 * (x) is restricted to x <= 4 .
