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:

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
