Polynomial Graphing - Exercise 1 - Graph a Factorable Polynomial

Find all the x-intercepts of f(x) = x^{4} - x^{3}
- 2x^{2} by solving x^{4} - x^{3} - 2x^{2}
= 0. Justify steps used to find x-intercepts. Then find some
other points and complete the graph. Verify the graph on a graphing
calculator.
