    Yes

    Step-by-step explanation:

    The inputs in a function should have only one output. In other words, each x value should only be assigned to one y value.

    For example, (-2, - 1), (1, 0), (1, 5), (2, 0) would not be a function because x value 1 is assigned to both number 0 and number 5.

    In (1, 1) (2, 2) (3, 3) (4,4), non of the X values repeat themselves, so it IS a function.
