coefficient

discrete graph

A graph is discrete when one (or both) of the variables has discrete entries, its means that are entered number, without decimal part, so the graph has no continuity, the trace will be broken parts, not a single one. 

continuous graph

a continuous graph is a graph where both variables are continuous, it means that their field's are de Real number, so the trace it's a continuous line.
