Chapter 3 review

We basically learned how to deal with polynomial function, long division, synthetic division, rational zero test, finding approximating zeros, and rational functions. For polynomial function, we learned that the a i are real numbers and are called coefficients, also the term an is assumed to be nonzero and is called the leading term. Then we learned how to use long division and synthetic division and we can use both way to divide functions. For approximating zeros, we divide the interval in half to find its midpoint and complete f(m).
