Question

Give the domain and range of the relation.

Answer 1

(a) D: {-5, 0, 4, 6}; R: {-9, 0, 9, 13}

Explanation:

The domain is the list of values in the x-column.

The range is the list of values in the y-column.

It is useful, but not essential, that the values be listed in numerical order.

x-values are 4, 6, 0, -5, so we can say the domain is {-5, 0, 4, 6}

y-values are 9, 13, 0, -9, so we can say the range is {-9, 0, 9, 13}
