Determine whether or not the equation represents y as a function of x. Please show work.
(x^3)y=-4
------------------------------------------ 
 = -4.

Yes, this relation determines y as a function of x: y = -.

This function is defined for all positive x: x > 0.

For each value of x, it determines one value of y (unique value of y.

For example, 

y(1)   = - = - = -4;

y(1/2) = - = - = -32;

y(2)   = - = - = -.
