Answer: To determine the domain and range of the given relation, we need to look at the set of all the x-coordinates (domain) and y-coordinates (range) of the ordered pairs in the relation.

Domain: The domain of the relation is the set of all x-coordinates. In this case, the x-coordinates are -1, 2, 1, 8, and 9.

Range: The range of the relation is the set of all y-coordinates. In this case, the y-coordinates are 2, 51, 3, 22, and 51.

To determine whether the relation is a function, we need to check whether each input (x-coordinate) has a unique output (y-coordinate). If there is any x-coordinate with multiple y-coordinates, then the relation is not a function.

In this case, we can see that there are two ordered pairs with the same x-coordinate of 2: (2, 51) and (-1, 2). Therefore, the relation is not a function.

Domain: {-1, 1, 2, 8, 9}

Range: {2, 3, 22, 51}

In Addition, It is not a function.
