B. The product xy is not constant, so the relationship is an inverse variation.


C. The product xy is constant, so the relationship is an inverse variation.


D. The product xy is not constant, so the relationship is not an inverse variation.


DISCLAIMER: IF THE ANSWER IS WRONG IT WILL BE REPORTED

Answer 1

The answer is D.

Explanation:

The x and y pairs shown in the table have product values: 818, 720 and 776. So the product xy is not constant and it is not an inverse variation. The answer is D.

Answer 2

D. The product xy is not constant, so the relationship is not an inverse variation.

Explanation:

If the relationship is inverse variation, then the product xy is constant.

2 · 409 = 818

3 · 240 = 720

4 · 194 = 776

The product xy is not constant.
