For A,  is defined on both sides of the y-axis, but is not” - For the function , the expression under the square root must be non-negative. So, the domain of is . It is only defined for non-negative values of , meaning it exists only to the right side of the -axis (in the first quadrant and along the positive -axis). For the function , we can take the cube root of any real number. So, the domain of is all real numbers, which means it is defined on both sides of the -axis.

For C, the graph of is not defined for all . Its domain is restricted to . So this statement is incorrect as it misrepresents the domain of
