Yes, the relationship between the total number of points scored and the player's jersey number is a function, as each jersey number corresponds to a unique total number of points scored throughout the season.
In the context of the roster listing the total number of points scored by each player throughout the season based on their jersey number, the relationship between jersey numbers and total points forms a function. A function is a mathematical concept where each input (in this case, the jersey number) corresponds to a unique output (the total number of points scored).
Since each player has a distinct jersey number, and the total points scored are associated uniquely with each jersey number, the roster fulfills the criteria of a function. This means that for any given jersey number, there is only one corresponding total number of points scored, validating the functional relationship between the two variables in the context of the roster.
