Chapter 5 Polynomials and Polynomial Functions - Graphing Calculator Activity - 5.2 Set a Good Viewing Window - Practice - Page 345: 6

$$x: [-5,10] \\ y: [-40,0]$$

In order to find a good window for a graph, first plug the equation into your graphing calculator. Next, go to the window, and change the viewing window until it gives a good image of the function. Be sure to include the minima and maxima in the window. Doing this, we find that a good window is: $$x: [-5,10] \\ y: [-40,0]$$
