Graph of a Polynomial

Most of the numbers - coefficients, the degree of the polynomial, the minimum and maximum bounds on both x- and y-axes - are clickable. To change a value up click (or drag the cursor to speed things up) a little to the right of the vertical center line of a number. Clicking on the left has the opposite effect.

See if you can predict (and explain) how a change in a coefficent effects the graph of the polynomial.


This applet requires Sun's Java VM 2 which your browser may perceive as a popup. Which it is not. If you want to see the applet work, visit Sun's website at https://www.java.com/en/download/index.jsp, download and install Java VM and enjoy the applet.


What if applet does not run?

Another applet helps investigate the behavior of polynomials depending on the distribution of their roots.
