Answer 2

The correct answer is inverse variation.

In an inverse variation, the product of the terms always remains the same. Consider the given values of x and y. For each row, the product of x and y is constant and equals 4.

So, the relation between x and y is inverse and the constant of proportionality is 4, the product of x and y.

The equation can be expressed as


`y= (4)/(x)`

Using, various value of x from the table will give you the corresponding y-values.

So the answer to this question is option C
