The Fundamental Theorem of Algebra

Use the [color=#0000ff][b]blue slider[/b][/color] change the [color=#0000ff][b]degree[/b][/color]. Then [b]move the graph up and down[/b] to change the number of real zeros (shown in [color=#ff0000][b]red[/b][/color]). Look for a connection between those values and the number of imaginary zeros (which can never be seen on a regular graph). This connection is a result of the Fundamental Theorem of Algebra.
