Question 1065977: If F = { (1,2), (3, 5), (4,7)} and G = { (1,4), (3,0), and (5, 2)}, what is F + G? What is G/F (using arithmetic function)?

You can put this solution on YOUR website!
Did you mean to have (4,7) as an element of F and (5,2)
as an element of G? That would mean that
F has domain {1,3,4} whereas G has domain {1,3,5}.
If you didn't make a typo, we can only use the common
domain {1,3}, and ignore the ordered pairs (4,7) in F
and (5,2) in G, since they do not have the same first
coordinate.
F+G = {(1,2+4), (3,5+0)}
or upon simplifying:
F+G = {(1,6), (3,5)}
---------------------
G/F = {(1,4/2), (3,0/5)}
or, upon simplifying:
G/F = {(1,2),(3,0)}
