Question 1039825
<pre><b>
The domain of {(i,8),(m,8),(l,8),(h,8)} is the set 
of all its first coordinates:

Domain = {i,m,l,h}

The range of {(i,8),(m,8),(l,8),(h,8)} is the set of 
all its second coordinates:

Range = {8,8,8,8}

But since they're all the same, there's no need to
write 8 but once, so:

Range = {8}
