Consider the function and its inverse.
f(x) = x² + 4 and ¹(x) = -
When comparing the functions using the equations, which conclusion can be made?
O The domain of f(x) is restricted to x ≥ 0, and the domain of ¹(x) is restricted to x > 0.
O The domain of f(x) is restricted to x ≥ 0, and the domain of f(x) is restricted to x ≤0.
O The domain of f(x) is restricted to x ≤0, and the domain of f1(x) is restricted to x = 4.
O The domain of f(x) is restricted to x ≤ 0, and the domain of ¹(x) is restricted to x ≤ 4.
