Question 1022211: I was given these sets: {(5,2), (5,6), (9,2), (9,6)}
{(-9,-3), (3,5), (9,9), (5,5)}
and told to determine whether the relation is a function. I must also "give domain and the range of the relation." Any help would be very much appreciated. Thank you.

{(,), (,), (,), (,)}
domain: all values of

range:all values of

{(,), (,), (,), (,)}
domain: all values of
,,,
range:all values of
,,

A is a set of ordered pairs in which x-element has only y-element associated with it.
Just remember:
A function may not have two y-values assigned to the same x-value, such as {(,), (,)}.
A function may, however, have two x-values assigned to the same y-value, such as {(,), (,)}.
as you can see here {(,), (,), (,), (,)} element has two y-element associated with it, and
also element has two y-element associated with it, and ; so, the relation is a function
{(,), (,), (,), (,)}
each is associated with one , even have two x-values assigned to the same y-value;so, the relation a function
