Make up two polynomial functions, f(x) and g(x).
• f(x) should be of degree 3 or higher. g(x) should be of degree 4 or higher.
• Find f(3) in each of the three ways: substitution, remainder theorem
(synthetic division), and long division. You should get the same answer
three times for f(3).
Find g(-2) once using your choice of the three methods.
