Question 889619: Help please.
Consider the relation defined by the following set of ordered pairs: {(0,4), (-2,0), (3,-1), (-4,0), (1-4)}
Is the relation a function?
What os the domain?
What is the range?

The format of the points is ( x,y )
To be a function, there must be a single value
of +y+ for any given +x+
This appears to be true
so, it's a function
-----------------
The smallest +x+ is +-4+ ( the point (-4,0) )
The largest +x+ is +3+ ( the point ( 3,-1)
So the domain is
+3+-+%28-4%29+=+7++
------------------
The smallest +y+ is +-4+ ( the point (1,-4) )
The largest +y+ is +4+ ( the point ( 0,4) )
So, the range is
+4+-%28-4%29+=+8+
