It is NOT a direct variation.

Only linear equation $y=ax$ represent a direct variation with a constant equal to $a$ .

The given equation is not a linear one (there is an exponent to which $x$ is raised), so it is not a direct variation.

Does the equation y=x^3y=x^3 represent a direct variation and if so, identify the constant of variation?
