Answer

Graph II represents a polynomial function.

Work Step by Step

In order to be a polynomial function, the graph must be a smooth and continuous line. There can be no sharp points/corners, and there can be no breaks or gaps in the line. With this, we can eliminate graphs I, III, and IV. This leaves us with graph II as the best representation of a polynomial function.
