Since the degree is an odd number, it will start and end in different directions.
A real root occurs when the polynomial intersects the $x$-axis, so this graph should intersect the $x$-axis $5$ times.

This polynomial has $5$ roots, but only $3$ $x$-intercepts.

A possible graph would be a polynomial with $3$ $x$-intercepts plus another bend.

The degree of this polynomial is even, so it starts and ends in the same direction.
