Check if the product of each pair of variables is constant.
No.
We want to check whether the relationship between the variables in the given table is an inverse variation. We can do this by calculating the product of each pair of x and y. Let's do this in a table.
| x | y | xy |
|---|---|---|
| 2 | 10 | 2⋅10=20 |
| 4 | 12 | 4⋅12=48 |
| 8 | 14 | 8⋅14=112 |
The product of each pair is not constant. Therefore, the relationship between the variables is not an inverse variation.
