Example 2:
The following is a set of polynomial functions and
their graphs. From the graphs determine the factors
(roots) of each polynomial and test them using your fx
calculator.

Looking at the graph, an estimate of the factors are,
= −3.05, −1.8, −1.2, 1
(feel free to choose your own estimates).
The keystrokes for your fx calculator are,
