1. 'S = {1,2,3,4,5}, A relation from S into S, g(n) = max{3,n}

Write down the image set and graph of this relation'

What does this 'max' thingy mean?

Thanks.

Best guess, it's just the maximume value of the elements in the set. e.g. max{1,4,7} = 7

Can't think what else they'd mean.

hmmmm.....thanks for your reply.....I'm gonna go over this again and see if it makes sense.
4. Seems to me that
g(1)=max{3,1}=3
g(2)=max{3,2}=3
g(3)=max{3,3}=3
g(4)=max{3,4}=4
g(5)=max{3,5}=5.

Those {} seem odd though.

Why not g(1)=max(3,1)=3 ?
