11 . Predict the end behavior of the function.
22 . Find the real zeros of the function. Check whether it is possible to rewrite the function in factored form to find the zeros. Otherwise, use Descartes' rule of signs to identify the possible number of real zeros.
33 . Make a table of values to find several points.
44 . Plot the points and draw a smooth continuous curve to connect the points.
55 . Make sure that the graph follows the end behavior as found in the above step.
