Use the table to determine the appropriate model of the function, x 1 2 3 4 5 f(x) 15 12 9 6 3 linear quadratic cubic exponential

The appropriate model of the function is:

                        Linear model

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:
