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.
