Is the relationship between the variables in the table a direct variation, an inverse variation, both, or neither? if it is a direct or inverse variation, write a function to model it. x 2, 5, 12, 20 y 30, 12, 5, 3

It is an inverse variation

 or  

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form or

In this problem we have

For >

For >

For >

For >

so

The function that model the table is

It is an inverse variation
