deltay/deltax= a constant of -3  This means that the velocity is constant, meaning this is a linear function.

The actual line is just f(x)= -3x+18

Answer:

The appropriate model of the function is:

                        Linear model

Step-by-step explanation:

We are given a table of values as:

           x               f(x)

           1                15

           2               12

           3                9

           4                6

           5                 3

Clearly we could observe that with each increasing value of x the value of function decreases by 3.

This means that the range of change is constant.

Hence, the relation is linear ( as the rate of change is constant )

Also, the equation that models this data set is given by:

                       [tex]y=f(x)=18-3x[/tex]
