What would be the range for {(-6, 4), (5, -1), (0, 3), (-2, 4)}

{4, -1, 3}

Explanation: The range is the set of all y-coordinates for our ordered pairs.

So the range for this relation is 4, -1, 3, 4.

Notice that we have two 4's as y-coordinates

but we only need to mention the 4 once.

So our range is {4, -1, 3}.

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
