The function f(x) = x^(1/3) is proven to be not Lipschitz continuous on the interval (-1, 1). The key argument involves examining the derivative |f'(x)| as x approaches 0, which diverges, indicating that no constant K can satisfy the Lipschitz condition abs(f(x) - f(y)) <= K * abs(x - y) for all x, y in the interval. This conclusion is reached by demonstrating that as x approaches 0, the slope of the function becomes unbounded.
