State whether the relationship between the variables in the table is a direct variation, an inverse variation, or neither. If it is a direct or inverse variation, write a function to model it.
x=3,9,13,20
y=9,27,39,60

I know it's direct but how do I write a function model to it?,

Respuesta :

The variation is a direct variation, and the function to model it is y = 3x

From the table, we can see that:

The y values are calculated by multiplying the corresponding x values by 3

Take for instance;

When x = 3, y = 9

When x = 9, y = 27

Using the above pattern, the function to model the table is y = 3x
