Sheila is playing a game with a 6-sided number cube. The number rolled determines the number of spaces moved. However, if a 3 is rolled, the player can choose to move 3 or 6 spaces. This mapping diagram shows the inputs and outputs for Sheila's game.

Does Sheila's mapping diagram represent a function? Why or why not?

Answer:

It is not because it includes the points (3, 6) and (3, 6) and fails the vertical line test.

Step-by-step explanation:

It does not represent a function because the same input value, 3, is mapped to more than one output value, 3 and 6. Her relation has the following ordered pairs: (1, 1), (2, 2), (3, 3), (3, 6), (4, 4), 5, 5), and (6, 6). Since both (3, 3) and (3, 6) have the same x-coordinate, the relation fails the vertical line test and is not a function.
