We don't know what your "graphing guidelines" are....




Factor the binomial by finding two numbers whose product is 1215 and whose difference is 18:



The graph should have zeros at -27, 0, and 45; its end behavior should be + for large negative values of x and - for large positive values of x.

A graph (window [-50,50,-100000,100000]....
