Graphing of Polynomial Functions Point by Point

Lew W. S.
This applet demonstrates how a graph of a given function is made up of points. A point (x, y) is an ordered pair of values where the corresponding value of the y coordinate is calculated by applying a value of x to the function.
Move the slider to obtain another value of x. Verify that the calculation of the y value using the function is correct. Observe the point P plotted for various values of x.
