You have the following inequality:

In order to determine which are valid solutions of the previous inequality, take into account that any positive value for V is solution of the previous equation, because if V is positive, 96/V is also positive.
Then, the following area solutions:
V = 3
V = 6
V = 8
V = 4
I think it would be (-y) to the power of -4. The exponents would add together to equal -4 while the y would just stay the same.
