Identify the type of function that models the situation below: a can of coffee is supposed to contain one pound of coffee. which function can be used to describe the difference in the actual weight of the coffee as compared to 1 pound? a. greatest integer function c. absolute value function b. step function

option c. absolute value function.

Justification:

The difference between two variables, W and P, is found subtracting on of the other.

Nevertheless, it is not stated which variable is the one that is going to be subtrated and which one will subtract.

Hence, the difference of such variables equals either to W - P or P - W. By using the absolute value function you can state:

                                  | W - P | = | P - W|,

which means that this function will return the difference no matter the order of the variables, i.e. no matter which subtract and which is subtracted.

In the case of the can of coffe, let be W the unknown weight of the can  and 1 the nominal weight (1 pound), then the difference is given by the following absolute value function:

                                                          | W - 1 |

With | W - 1 |, you will determine how har is the weight of the can of coffe from its nominal value of 1, no matter wheter the weight is greater or less than 1 pound.
