Question 855305
Every function has x and y coordinates.  (x,y).  The domain is the possible x-coordinates.  The range is the possible y-coordinates.<P>
When given a set of (x,y) ordered pairs, the domain is all the given x values.  The range is all the possible y values.<P>
For this problem, the domain is {4,6,8} and the range is {4,16,64}.
