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