Question

Determine whether the relationship is an inverse variation or not. Explain.

Answer 1

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

Explanation:

For it to be an inverse variation, the product of x and y must be constant.

• For the first row, xy=2(424)=848.
• For the second row, xy=3(280)=840.
• For the third row, xy=4(210)=840.

This means the product xy is not constant, so the relationship is not an inverse variation.
