The graphs y=x
3
and y=x^(1/3) are shown together. Which relationship is correct?
A
They are reflections across the x-axis, and only y=x^(1/3) has all real domain.
B
They are reflections across the y-axis, and both have range y >= 0.
C
They are reflections of each other across the line y=x, and both have all real domain and range.
D
They have the same graph because 3 and 1/3 are reciprocal exponents.
