Hi there!

I can't understand an exercise with binary relations, could somebody explain it to me?

For each of the following binary relations on A={1,2,3,4,5} draw its directed graph. Then by examining the graph decide whether the relation is 1) reflexive, 2) symmetric, 3)antisymmetric, 4) transitive.

a)SquareOf defined by $\displaystyle SquareOf(x,y)$, when $\displaystyle y=x^2$

How do I do it? How do I draw a graph? I'm looking through my notes,but can't find the answer :-( Please help
