Question

Show all the stepsx: 3, 9, 13, 20y: 9, 27, 39, 60State 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.

Answer 1

By looking at the table, we can see that the y values are equal to the x values multiplied by 3.

3x = 3*3 = 9

3x =3*9 = 27

3x=3*13=39

3x= 3*20= 60

So, it is a direct variation and the function is y=3x
