For the function defined by y = 1/x^4, y varies inversely as what quantity? a. x^2
b. 1/x^4
c. y
d. x^4

ANSWER
y varies inversely as x exponent 4.
EXPLANATION
The inverse variation equation is given as:

We can see that there is an inverse relation between the quantity y and x.
If the it were , we say y varies inversely as the square of x.
Hence for the given relation,the precise definition is that, y varies inversely as x exponent 4.
