Quizplus · Accepted Answer

A function assigns exactly one output to each input. In this table, the days in January are the outputs and the weights are the inputs. Since multiple days correspond to the same weight (e.g., 218 lbs corresponds to January 1 and January 4), the relationship does not define the day as a function of weight.
