For any function y=f(x) - if a point (x,y)
is on the of graph, then y=f(x) (duh);
is above the graph, then y>f(x);
is below the graph, then y<f(x).

Say, for f(x)=x^2:
if x=2 then f(2)=4 and the point (2,4) is on the graph.
For the point (2,5): 5>f(2);
For the point (2,3): 3<f(2).

Time to hit the sack, man!
talking to myself. bad sign
