Sketching the Graph of a Polynomial Function
Graphing Polynomial Functions Using a Table of Values Example #1
Plug in values for x (-2, -1, 0, 1, and 2 are recommended) to get y values, and plot your points (x, y). Connect your points to form the graph.
Graphing Polynomial Functions Using a Table of Values Example #2
Graphing Polynomial Functions Using It's Intercepts Example #1
Factor the polynomial completely, to find all of it's x-intercepts. The y-intercept is the polynomials constant term. Look at the degree (even/odd) and the leading coefficient (positive/negative) to determine the behavior of the graph. Plot the x and y intercepts, and connect the points to form the graph.
