Polynomial Graphing - Exercise 1 - Graph a Factorable Polynomial
Find all the x-intercepts of f(x) = x4 - x3
- 2x2 by solving x4 - x3 - 2x2
= 0. Justify steps used to find x-intercepts. Then find some
other points and complete the graph. Verify the graph on a graphing
calculator.

JUSTIFICATION
f(x) = x4 - x3
- 2x2
Solve x4 - x3 - 2x2
= 0 in order to find x-intercepts
