... To prove the minimal property of 33, we have to construct a graph with 32 edges such that it has no red triangle or blue triangle. From the first part of the proof, we see that there should not be a complete subgraph of 6 vertices if no red or blue triangle appears. To avoid such a complete subgraph ...

If a vertical line passes through more than one point on the graph of a relation, the relation must have more than one point with the same x-coordinate. Therefore the relation is not a function. ...
